Daysake Privacy Policy
Daysake is a private notebook for parents. You write down a line about your child's day, and Daysake keeps it as a page with the date and your child's age at the time. This policy explains what information we handle, why, where it is stored, how long we keep it, and how you can see, download, or delete it.
The short version:
- Daysake is for adults who are a child's parent or legal guardian, and for family members they invite. Children do not have accounts and do not use the app.
- Your family's pages are private to your family. There is no public feed, no likes, and no followers.
- We do not show ads. We do not sell or share your personal information. We do not use your pages or photos to train AI.
- You can download everything for free and delete your account in the app at any time. A page you delete disappears at once and is deleted for good within 30 days.

2. Who can use Daysake, and what it does
You can create a Daysake account if you are 18 or older, or the age of majority where you live if that is higher, and you are either a parent or legal guardian of the child, or a family member a parent or guardian has invited to keep the notebook with them. Our Terms of Use say the same.
Daysake lets you:
- create an account (email and password, Sign in with Apple, or Google; signing up with Kakao is offered when the app is set to Korean, and Kakao accounts can sign in whatever the app's language),
- add a child's name or nickname and birth month or birthday,
- write short pages and answer a weekly question about the child,
- attach one photo to a page (optional, with separate permission),
- invite another parent or family member to write in the same notebook,
- download everything as a PDF or a ZIP file, and delete your account.
Daysake does not:
- store original photo files (only smaller copies),
- use the camera, recognize faces, or guess emotions from photos,
- record or store voice,
- take payments,
- publish anything publicly or offer likes, comments, followers, or rankings,
- score, rank, or compare children, or assess development, health, personality, or future careers,
- use advertising identifiers or third-party ad tracking,
- send your pages or photos to outside AI services or use them to train AI.
3. Information we collect and why
You give us most of this information directly. Information about your child is always entered by an adult in the family, not by the child.
| Information | Why we use it | When |
|---|---|---|
| Account details: email address (if provided), account ID, and the sign-in ID from Apple, Google, or Kakao | To sign you in and recognize your account | Always |
| Your name in the notebook (or the first part of your email address as a default) | To show who wrote a page | Always |
| Family notebook ID and your role in it | To make sure only your family can see your family's pages | Always |
| Record of what you agreed to (that you are the child's parent or guardian or were invited by one, these policies, and storage of what you write) | To show that you gave these confirmations | Always |
| Child's name or nickname | To label your child's notebook | Always |
| Child's birth month or birthday | To show your child's age on each page | Always |
| The text of your pages, exactly as you wrote them | This is the notebook itself. We never overwrite the original text | Always |
| Who can see each page (your family, or "Just me") | "Just me" pages, with their photo, notes, and thanks, are visible only to the person who wrote them. Others in the family (including the person who looks after the family notebook) cannot see them, and no notification is sent | Always |
| The weekly question and the words you actually used to ask it | To show your child's answer together with the question. Answers are kept like other pages and are visible only to your family | If you answer a question |
| What your child calls you (for example, Mom, Dad, Mum) | To show who wrote a page and to use in question wording | Optional |
| Which weekly question each person was given (person, child, skipped questions, week) and its reminder text | To give each person a different question, avoid repeats, and send reminders at the time you chose. Visible to your family | If you use the Questions tab |
| History of date or child changes to a page (old and new value, who changed it, when) | To keep the original page while recording changes | If you change a page's date or child |
| A photo you attach to a page: a smaller display copy, a thumbnail, and a print copy (smaller than the original) | To show the photo with its page, and to print a book if you order one | Optional |
| Kind of page (something said, a first, into lately, funny moment, just today) | To group pages | Optional |
| Edit history of your pages | To show the latest version and the date it was edited, while keeping the original | If you edit |
| Notes you add to a page and "thanks" taps | To let people in the same family add a note or say thanks | Optional |
| Your family's time zone and your app language | To date pages by your family's local day, send reminders at your local time, and write notifications in your language | Always |
| Invite code passed through Google Play (Android) | If you install Daysake from an invite link on Android, Google Play hands the invite code to the app once, on first launch, so the invite is filled in for you. It is not used for anything else | Only when you install from an invite link on Android |
| Invite code you paste (iPhone) | On iPhone, the invite page copies the code to your clipboard. The app reads the clipboard only when you tap Paste on the invite code screen | Only when you tap Paste |
| Product analytics events (Section 4) | To see where people get stuck between sign-up and the first page, whether they come back, and whether question reminders are used | Only if you turn it on |
| Crash reports (what error happened and where in the app's code, the names of the last screens visited and the server addresses called (with IDs removed) and their results, device model and state such as memory and screen size, operating system and app version, and language and time zone; we have turned off IP address storage in our crash reporting, so no location is derived from it) | To find and fix crashes and errors | When an error happens |
| Push notification token (created by Expo for each device that allows notifications), device type (iPhone or Android), and app version | To notify you when someone in your family adds a page or a note, and to send the weekly question at the time you chose | If you allow notifications |
| Question reminder settings (on or off, day and time) and whether this week's reminder was sent | To send the reminder at the right time and not twice in the same week | If you turn on question reminders |
| Server and website request logs: IP address, time, the address requested, the result, and device or browser type | To run, secure, and troubleshoot the service. Kept by our hosting providers: Supabase for up to 7 days, Cloudflare for a short period under its own policy | Every time the app or website talks to our servers |
| Security and activity logs (for example, invites sent and accepted, changes to who looks after the family notebook, notebook deletions, and account deletions and their outcome) | To check access and requests and to show how we handled them | When these actions happen |
We may count how many pages are saved on each day as plain numbers that do not identify anyone. We do not read the content of pages to do this.
Crash reports in more detail
Before a crash report leaves your phone, the app is built to hide page text, answers, your child's name or nickname, what your child calls you, people's names and email addresses, values in quotes, and runs of ordinary words that read like sentences, in any language. Very short phrases may not be hidden. It keeps the parts of an error that look like code. Crash reports do not include your account ID or family ID, and our Sentry project is set not to store IP addresses. Screen recording, screenshots, and performance tracking are turned off. On its own, a crash report is hard to link to a person, but because it could be linked when combined with other information, we treat it as personal information.
Push notifications in more detail
Notifications contain only what your child calls the person who wrote (for example, "Mom"), a fixed sentence such as "added a new page", or the text of this week's question. In question reminders, your child's name is replaced with "your child". Notifications never include page text.
4. Choices you make in the app
When you sign up, you confirm three things: that you are the child's parent or guardian (or were invited by one), that you agree to this policy and the Terms of Use, and that Daysake may store what you write. We keep each consent separately. We do not ask for broad consent up front. When a feature needs more information, the app asks the first time you use it.
Photos. We ask for permission the first time you open your photo library from Daysake.
- What we store: a smaller display copy, a thumbnail, and a print copy (smaller than the original) of the photo you choose. Your original file stays on your phone.
- Why: to show the photo with its page, and to print a book if you order one. We do not use the print copy for anything else.
- How long: as long as the page exists. If you delete the page or your account, the photo copies are deleted too.
- If you say no: you can keep writing. You just cannot attach photos.
Product analytics (off by default). We collect product analytics only if you turn it on, either with the unticked box on the sign-up screen or later in Settings › How we look after your pages › Usage stats.
- What we collect: a random number created on your device, the date (no time of day), a running count kept on the device, and only the events and details listed next.
- Events: signing in (with Kakao, Apple, Google, or email); opening the notebook for the first time (from a draft or from setup); skipping the first page (and where: later, the notebook, or a question); opening the Questions tab; starting an answer; saving the first page (from the Write tab or a question, with or without a photo, and whether you had skipped before); viewing the notebook for the first time; opening the app on a new day (how many days since you started, 0 to 31); opening a question reminder (the kind of question: jot down, watch and write, ask, or none); and saving a question answer (the kind of question, and whether it came from this week's question, an extra question, a day that comes to mind, the birthday questions, or elsewhere).
- Never collected in analytics: page text or its length, the question or the answer, your child's name or birthday, your name or email, your account ID, or advertising IDs.
- How: the server checks only that the signed-in person has turned analytics on, then stores the events under the random device number, not under your account. Like every request to our servers, the request that sends them briefly appears in our hosting provider's request logs with your connection's IP address; we do not use those logs to link events to you. Because a small number of users means events could in theory be linked back to someone, we treat them as pseudonymous data.
- How long: deleted automatically every day once they are 6 months old.
- Turning it off: you can turn it off at any time. When you do, the events stored under that number are deleted. Every feature works the same whether analytics is on or off.
Notifications. Notifications about pages and notes from others in your family start when you allow phone notifications while setting up a shared notebook. You can turn each kind off in Settings › Notifications. Question reminders are sent only if you turn them on, and you can turn them off in the same place. If you do not allow notifications, you still see what's new when you open the app.
We will not use any future feature (such as voice, AI summaries, long-term storage plans, or payments) under the consent you gave at sign-up. If we add one, we will explain what it collects, why, for how long, and how to stop, and ask you first where required.
Inviting someone to write, and accepting an invite, is recorded as its own consent.
5. Legal bases (UK, EEA, and similar laws)
If UK GDPR or EU GDPR applies to you, we rely on:
- Contract: to provide the notebook you signed up for (account, child details, pages, writing together, downloads, deletion).
- Consent: for photo storage, product analytics, and push notifications. You can withdraw consent at any time in the app. Withdrawing does not affect what we did before.
- Legitimate interests: for crash reports, request logs, security logs, and keeping records of requests. Our interest is keeping Daysake working and secure and being able to show how we handled requests. We limit this data as described above.
- Legal obligation: where the law requires us to keep or disclose information.
Pages you write may sometimes mention your child's health (for example, "had a fever today"). We do not ask for health information and we do not analyze pages for it. We store it only as part of your private notebook, at your direction. See also our Consumer Health Data Privacy Policy: https://daysake.com/en/consumer-health-data/
6. Service providers and where your data is stored
We use the service providers below to run Daysake. They process information only on our instructions and only to provide their service.
| Provider | What they do | Information | Location |
|---|---|---|---|
| Supabase, Inc. | Sign-in, database hosting, access control | Account details, family, child, page, and consent records; product analytics events (if on); request logs | Tokyo, Japan (Northeast Asia region). Supabase is a US company |
| Supabase Storage | Stores photos attached to pages | Photo display copy, thumbnail, print copy | Tokyo, Japan. Each family's photos are stored under that family's ID, and access rules block anyone outside the family |
| Functional Software, Inc. (Sentry) | Crash reports | Crash reports (Section 3) | Stored in Frankfurt, Germany. Sentry is a US company, so its staff may access data from the US for operations and support. Sentry's subprocessors: https://sentry.io/legal/subprocessors/ |
| 650 Industries, Inc. (Expo) | Passes push notifications to Apple and Google | Push token, notification title and body, and an ID that tells the app which notebook, page, or question to open | United States |
| Apple Inc. (Apple Push Notification service), Google LLC (Firebase Cloud Messaging) | Shows notifications on iPhone and Android | Same as Expo | Apple's and Google's servers worldwide |
| Resend, Inc. | Sends account emails (sign-up confirmation, password reset) from [email protected] | Your email address and the email content | Japan (Tokyo) |
| Cloudflare, Inc. | Hosts the daysake.com website, including the invite page, and forwards emails sent to our @daysake.com addresses to our inbox | Website request logs (Section 3); emails you send us | Cloudflare's global network |
| Google LLC (Gmail) | Our inbox: receives the emails Cloudflare forwards, so we can answer you | Emails you send us | United States and Google's servers worldwide |
Sign in with Apple and Google. When you sign in with Apple or Google, we receive only what we need to sign you in. From Apple, we receive an account ID and an email address (or a relay address if you choose "Hide My Email"). From Google, we receive an account ID and an email address. Google also sends your name and profile photo address; these stay in the sign-in record, but the app does not use or show them. If you use Kakao sign-in (offered for sign-up when the app is set to Korean), from Kakao we receive a member number and, if you agree on Kakao's screen, your Kakao account email. We never send your child's name, pages, or photos to Apple, Google, or Kakao.
We do not otherwise disclose your personal information to anyone, except when the law requires it, when you clearly ask us to, or to the service providers above.
7. International transfers
Daysake is run from the Republic of Korea. Your information is stored in Japan (Supabase; account emails are sent through Resend's Tokyo region) and Germany (Sentry crash reports), and some of it is handled in the United States (Expo, and support access by Resend, Sentry and Supabase). This means your information may be processed outside the country where you live, including in countries whose privacy laws differ from yours.
- Japan and the Republic of Korea are recognized by the European Commission and by the UK as giving adequate protection to personal information.
- Germany is in the EU.
- For transfers to the United States, we rely on the safeguards our providers offer, such as the EU Standard Contractual Clauses with the UK Addendum, or the EU–US Data Privacy Framework and its UK Extension where the provider takes part.
- Data is encrypted in transit and, at our hosting provider, at rest.
You can ask us at [email protected] for more detail about these safeguards.
8. How long we keep information
| Information | How long |
|---|---|
| Your account, family notebook, child details, and pages | Until you delete them or your account, or until we close Daysake after the advance notice described in Section 10 of the Terms of Use |
| A page you delete | Gone from the notebook at once. Its photo copies are removed from storage at once, and the page itself, with its notes, edits, and change history, is deleted for good within 30 days |
| Photos | As long as the page they belong to. We do not keep photos apart from their page. Question answers, the words you used to ask, and change history are kept and deleted with their page |
| "Just me" pages | Deleted, with their photos, when the person who wrote them deletes their account. If that person only leaves the notebook, the pages stay but remain hidden from everyone else |
| Consent records | Deleted together with your account |
| Product analytics events | Deleted automatically once they are 6 months old |
| Crash reports | 30 days from collection |
| Server and website request logs | A short period set by our hosting providers (Section 3) |
| Security and activity logs, including the record that an account was deleted (a random account ID, the date, and the result; never your child's details, pages, or photos) | 1 year, then deleted automatically |
| Push tokens | Deleted when you sign out or delete your account. If a token stops working (for example, the app was uninstalled), we delete it the next time a notification to it fails |
| Question reminder settings and send history | Deleted with your account |
| Copies in our hosting provider's automatic backups | Overwritten within 7 days |
9. Deleting your information
Delete a page. Open the page, open its menu (⋯), and tap Delete. The page disappears from the notebook and from your downloads at once. Any photo, thumbnail, and print copy are removed from storage at the same time, and the page itself is deleted for good within 30 days. If the person who looks after the family notebook deletes a child's notebook, we remove all of that child's photos first and then delete the notebook and its pages.
Leave a shared notebook. Settings › Leave this notebook. You can no longer see the notebook, and everything you wrote stays in it for the others. Your "Just me" pages stay hidden from everyone.
Delete your account in the app. Go to Settings › Delete my account. This deletes your account right away.
- If you are the only person in your family notebook, the whole notebook is deleted: children, pages, notes, and all photos.
- If others write in your notebook with you, only you are removed. The pages you wrote stay in the notebook for them without your name: they show as written by "Someone writing with you" in the notebook and by "Family member" in downloads. Your "Just me" pages and their photos are deleted. If you looked after the family notebook, that role passes to the person who joined first. If you also want the shared pages you wrote removed, delete them before you delete your account, or email us.
- Your consent records are deleted with your account. We keep only the record that the account was deleted (Section 8).
- If you signed in with Apple or Kakao, we also disconnect Daysake from that account.
- If product analytics is on, the app deletes your analytics events before deleting the account.
Delete your account without the app. If you cannot sign in or no longer have the app, use https://daysake.com/en/delete-account/ or email [email protected] from the email address on your account. To make sure the request comes from the account holder, we send a short code to that email address and ask you to send it back. We do not ask for ID documents. If you used Apple's "Hide My Email", tell us the relay address and we send the code there. We reply within 7 business days, and once the code is confirmed we delete the account as described above.
Crash reports are not linked to your account, so we cannot find and delete them one by one. They are deleted automatically after 30 days. Reports not yet sent stay on your phone and are removed if you uninstall the app.
Analytics on an uninstalled phone are not linked to your account, so they are deleted automatically once they are 6 months old.
10. Downloading your information
You can download your family's notebook for free at any time in Settings › Download everything.
- Writing only gives you one PDF with the date and age on every page.
- Writing and photos gives you one ZIP file with a PDF for each child, the stored photo copies (the print copy if there is one, otherwise the display copy), and a list of pages (records.json).
- Edited pages include the original wording. Deleted pages are left out. Notes added to pages are included with the name of the person who wrote them. Your own "Just me" pages are included only if you choose to include them.
- The file is made on your phone and handed to your phone's share sheet. We do not create or keep download files on our servers.
11. Children's privacy
Daysake is meant for adults: parents and legal guardians, and the family members they invite. It is not directed to children.
- Children do not have accounts and do not sign in. You must be 18 or older, or the age of majority where you live if that is higher, to create an account.
- Children under 13 (or under the age of digital consent where you live) do not use Daysake. We do not knowingly collect personal information directly from children.
- Information about a child (name or nickname, birth month or birthday, pages, and photos) is provided by the parent or guardian, or by a family member they invited, and the family controls it. They can review, download, correct, or delete it at any time in the app, or by emailing [email protected].
- We do not use children's information for advertising, profiling, or AI training, and we do not disclose it to third parties except the service providers in Section 6.
- If you believe a child has created an account or given us information directly, email [email protected] and we will delete it.
12. No ads. No sale or sharing of personal information
- We do not show ads and we do not use advertising identifiers or ad tracking.
- We do not sell your personal information, and we do not "share" it for cross-context behavioral advertising, as those terms are used in the California Consumer Privacy Act (CCPA/CPRA). We have not done so in the past 12 months.
- Because we do not sell or share, there is nothing to opt out of. If your browser sends a Global Privacy Control signal, we treat it as an opt-out request anyway.
- We do not use sensitive personal information to infer characteristics about you or your child.
13. Consumer health data (Washington, Nevada, and similar laws)
Daysake does not ask for health information, and it does not diagnose or assess children. But you might write something like "had a fever" or "went to the doctor." Under some US state laws, such as the Washington My Health My Data Act, that could count as consumer health data. We collect it only because you chose to write it, use it only to keep and show your private notebook, never sell it, and share it only with the service providers in Section 6. You can see, download, and delete it at any time.
Our separate Consumer Health Data Privacy Policy explains this in full: https://daysake.com/en/consumer-health-data/
14. Your rights
Everyone can, at any time:
- see and download their family's information (Settings › Download everything),
- correct pages and child details in the app,
- delete pages, a child's notebook, or their account,
- withdraw consent for photos, analytics, or notifications in the app,
- ask us questions or make a request at [email protected].
We reply within 7 business days and complete requests within the time the law requires. To confirm a request comes from you, we use the email code described in Section 9. If a request concerns information where guardian rights are unclear or disputed, we may restrict access, ask for more information, or pause the request while we check.
UK, EU, and EEA (including Ireland). You have the right to access, correct (rectify), and erase your information, to restrict or object to our processing (including processing based on legitimate interests), to data portability, and to withdraw consent at any time. You can complain to a data protection authority. In the UK, that is the Information Commissioner's Office (ico.org.uk). In Ireland, it is the Data Protection Commission (dataprotection.ie). In other EU countries, it is your local authority. We would appreciate the chance to help first at [email protected].
California and other US states. Depending on where you live, you may have the right to know what personal information we collect, use, and disclose; to access and get a copy of it; to correct it; to delete it; and to opt out of sale, sharing, or targeted advertising (we do none of these). We will not treat you differently for using these rights. You can use an authorized agent; we may ask the agent for proof of permission and ask you to confirm the request with the email code. If we deny a request, you can appeal by replying to our answer or emailing [email protected] with "Appeal" in the subject.
Australia. We handle personal information in line with the Australian Privacy Principles. You can ask to access or correct your information. If you are not satisfied with how we handle a complaint, you can contact the Office of the Australian Information Commissioner (oaic.gov.au).
Canada. You can ask to access and correct your information and withdraw consent, as provided by PIPEDA and provincial laws. If you are not satisfied with our answer, you can contact the Office of the Privacy Commissioner of Canada (priv.gc.ca).
New Zealand. You can ask to access and correct your information under the Privacy Act 2020, and complain to the Office of the Privacy Commissioner (privacy.org.nz).
Singapore. You can ask to access and correct your information and withdraw consent under the Personal Data Protection Act 2012, and contact the Personal Data Protection Commission (pdpc.gov.sg).
15. How we protect information
Every child and page is tied to a family notebook ID. Database access rules let a person see only the family notebooks they actively belong to. People join with an invite link or code and their own account, never by sharing a password.
An invite code works for 2 weeks and for one person. Anyone holding the code sees the name of the person who sent it. After signing in, and before joining, they also see the children's names (up to two), the number of pages, and how many people write in the notebook. Send the link only to the person you mean to invite.
Our staff access your family's information only when it is needed to fix a problem you report or we detect, to handle a request you make, or when the law requires it. Data is encrypted in transit, and our hosting provider encrypts stored data at rest. No system is perfectly secure, but we limit what we collect so there is less to protect.
16. Changes to this policy
If we change this policy, we will tell you in the app or by another reasonable means before the change takes effect, and we will update the version and date at the top. If a change needs your consent, we will ask for it.
This policy is published in English and Korean, and both describe the same practices. If the two versions ever differ, the version in the language you use the app in applies.
17. Contact
- Privacy questions and requests: [email protected]
- Account deletion: [email protected]
- Everything else: [email protected]
Change history
- Version 1.0 (English), effective 2026-11-03: first English version. It describes the same practices as the Korean policy, including its amendment effective 2026-11-09 (time zone and language, deleted pages removed for good within 30 days, security logs kept for 1 year).
