Privacy Policy

Effective November 15, 2026

Kinboard is a family calendar board for parents. This policy explains what information the Kinboard iPhone app and this website, including the family board at kinboard.family/board, collect, why, who can see it, and how to delete it. We collect only what the app needs to keep your family's board in sync. We don't show ads, we don't sell your information, and we don't track you across other apps or websites.

What we collect

What you put on your board

Everything you add to a board is stored on our servers so it can sync to every parent's phone on that board:

• Family cards: the names you give each person (for example "Mom" or a child's first name), their marker color, and, for children, the school and grade you enter.
• Calendar marks: the text, dates, times, repeats, and done check marks of what you write on the calendar.
• Newsletters: the text of school newsletters you paste in, and the dates found in them. Kinboard reads the dates on your phone with built-in rules. Newsletter text is never sent to an AI service.

Account information

• A random account ID. When you first open Kinboard on an iPhone, it creates an anonymous account with a random ID. In the app, you don't give us a name, email address, or phone number.
• Web login (the board in a browser only). To use the family board in a browser at kinboard.family/board, you sign in with Google or with a link sent to your email address, so you can get back in from another computer or after clearing your browser. We keep your email address with your account and use it only to sign you in and to send sign-in links you ask for. If you choose Google, Google also shares your name and profile picture with our sign-in service; we don't use them. Other parents on your board don't see your email address.
• Sign in with Apple (optional). If you choose "Save your board," your account is linked to your Apple ID so you can get the board back on a new phone. Kinboard asks Apple for no name and no email. We receive only an identifier Apple creates for Kinboard.
• Family membership and invites. Which board your account belongs to, which parent card it joined as, and the invite codes you create or redeem. Invite codes expire after 7 days or once they're used.

Purchases

Subscriptions are bought through Apple's App Store. We never see your payment card or billing details. We use RevenueCat to check subscription status. It receives your random account ID and the App Store record of your subscription: which plan, when it started, renews, or ends, and any refund. We store on the board which account pays and until when, so one subscription opens the board on every parent's phone.

Technical information

To run and protect the service, our providers process technical information that comes with every request, such as IP address, device and operating system type, and server logs. Kinboard uses Firebase App Check, which uses Apple's App Attest or DeviceCheck to confirm that requests come from the real Kinboard app. Kinboard has no advertising tools.

Anonymous usage counts

To learn which features families use and what breaks, Kinboard counts things that happen in the app, such as "a newsletter was added and 6 dates were found," "a page was opened," or "saving to the board failed." These counts never include anything on your board (names, schools, calendar text, notes, or newsletters), your account ID, or your Apple ID. They come with general device details such as the iPhone model, iOS version, app version, language, and region. They're sent to TelemetryDeck, which tells phones apart only by a scrambled (salted and hashed) form of the ID Apple gives Kinboard on your phone, so counts can't be tied to you or your family. Kinboard doesn't use the advertising identifier and doesn't track you across apps. You can turn this off anytime in Settings → Share anonymous usage; when it's off, nothing is sent.

Visiting this website

When you open a page on this website, we count the visit, and any tap on the App Store button, with TelemetryDeck: which page, the page that linked you here, your browser's language, and general details such as browser type and country. This website's pages don't use cookies. The board page keeps you signed in by saving your login in your browser's storage, and if you choose Continue with Google, Google's sign-in window uses Google's own cookies. TelemetryDeck tells visitors apart only by a scrambled (salted and hashed) form of your IP address and browser details that changes every day, so visits can't be tied to you or followed across days or other websites.

Everything you post on Feature requests is public. Leave out names and anything private. The page keeps a random voter ID in your browser's storage so each browser's vote counts once. The ID isn't a cookie and isn't sent anywhere else. It goes away when you clear your browser's data. To stop one home from voting many times, we store a scrambled (salted and hashed) form of your network address with each vote and each idea you post. It can't be turned back into the address. Email us to have an idea you posted taken down.

Settings that stay on your phone

Your sound, light or dark mode, and usage-sharing choices are stored only on your phone.

How we use it

• To show and sync your board on every parent's phone on it.
• To let parents invite each other, and to restore a saved board on a new phone.
• To run the 14-day free trial and work out whether the board's subscription is active.
• To see which features get used and fix what breaks, from anonymous usage counts you can turn off.
• To keep the service secure and prevent abuse.
• To answer you when you contact us.

We don't use your information for advertising or profiling, and we don't use it to train AI models.

Who can see it

• Parents on your board. Everyone who joins your board with an invite code can see and change everything on it, including newsletters. Only invite people you trust.
• Our service providers, who process data for us under their own privacy and security terms:
  • Google Firebase (Authentication, Cloud Firestore, Cloud Functions, App Check) stores and syncs board data, keeps web logins, and sends email sign-in links. These services run under the Google Cloud terms, which say Google won't use our data to train or fine-tune AI models without our permission (Service Specific Terms, Section 18 "Training Restriction"). We have never given that permission. Firebase privacy
  • RevenueCat checks subscription status. RevenueCat privacy
  • TelemetryDeck receives the anonymous usage counts and website visit counts. TelemetryDeck privacy
  • Google also handles Continue with Google on the board page. Google privacy
  • Apple handles Sign in with Apple, App Store purchases, and App Attest. Apple privacy
• When the law requires it. We may disclose information if required by law, or to protect the safety of our users or others.

We don't sell or rent personal information, and we don't share it for cross-context behavioral advertising.

Children

Kinboard is meant to be used by parents and guardians. Children don't have accounts. A parent may add a child's first name, school, and grade to a card on their family's board; that information is visible only to the parents on that board. We don't knowingly collect personal information directly from children under 13. If you believe a child has given us personal information, contact us and we'll delete it.

How long we keep it, and how to delete it

We keep your board while someone is on it, with about a year of past weeks. Each night, calendar marks and newsletters whose last day is more than a year ago are erased automatically. A repeating mark, like a birthday, is kept until its last time is a year past. You can remove your information yourself in Settings, in the app or on the board page:

• Clear past weeks erases every calendar mark and newsletter that was over before this week, for everyone on the board. Repeating marks that are still going stay.
• Leave this board takes you off the board and erases your parent card and the calendar marks written for you. If you're the last person on the board, the whole board is erased, including its people, calendar, and newsletters.
• Delete my data does everything above, and also erases the invite codes you made or used, deletes your account, including your email address and web login, and in the app revokes Sign in with Apple for Kinboard.

A board that other parents are still on stays with them. If another parent removes you, your card is deleted, but marks written for you stay on the board under "Everyone."

Deleting your data doesn't cancel an App Store subscription. Cancel it first in Settings on your iPhone, under your name → Subscriptions. Apple and RevenueCat keep their own purchase records as required for billing, tax, and accounting. You can ask us to delete the RevenueCat record linked to your account.

Our providers' server logs and backups may keep copies for a limited time before they're deleted automatically.

Your rights

Depending on where you live, including the EU, the UK, and California, you may have the right to access, correct, export, or delete your personal information, to object to or restrict how it's processed, and to complain to your local data protection authority. Most of this you can do in the app or on the board page: edit or erase anything on the board, or use Delete my data. For anything else, email us. We'll answer within 30 days and won't treat you differently for asking.

Where the GDPR applies, we process your information to provide the service you asked for (performance of a contract), and to keep it secure (our legitimate interests).

Where it's stored, and security

Your information is stored on Google Cloud servers and may be processed in the United States or other countries where our providers operate. Data is encrypted in transit and at rest. Our database rules let only the parents on a board read or change it. No system is perfectly secure, so please keep your phone locked and invite only people you trust.

Changes to this policy

If we change this policy, we'll update the date at the top. If a change is significant, we'll also let you know in the app before it takes effect.
