Privacy Policy

1. Information You Give Us

Account details: your email address, a display name and handle, and an optional profile photo. Sign-in is passwordless — we send a one-time code to your email rather than storing a password.

Date of birth: joining a challenge with an entry fee requires confirming you are at least 18. We store the date you provide to enforce that rule. Stint is not intended for anyone under 18.

Challenge choices: the focus challenges you join, the apps you select as "work apps" (which count toward focus time), the apps you choose to block, and any emergency or social-app allowances you request.

Messages: what you post in a challenge’s group chat, plus any reports you file or members you block.

Waitlist and support: if you join the waitlist or contact us, we keep the email address and any details you include.

2. Information Collected Automatically

Focus verification data: while a session is running, each of your devices that takes part sends periodic, server-verified reports of how your time was spent, minute by minute, in broad categories: work, a blocked app or site, the block screen, an allowed emergency or social app, or neither. This is how challenge results are decided fairly for everyone in the pool. It records time per category, not what you did inside an app.

On your phone, the apps you pick stay on the device. From iPhone we receive only a fingerprint (a one-way hash) and a count for each of your app lists, so we can tell if a list changed during a challenge. From Android we receive no app names; the Android app reports seconds spent on its block screen and in blocked apps, which can end a challenge day.

Screen Time data stays on your device: app selection happens through Apple’s Family Controls picker, which gives Stint opaque tokens. We never see the names of the apps you chose, and Apple does not share your usage of them with us.

Usage and diagnostics: we use Mixpanel to understand how the app is used — screens visited, onboarding steps, features used — and diagnostic reports, so we can fix problems and improve Stint. These events are associated with your account.

Device and account identifiers: an identifier for your account, an identifier for each device you link (an install identifier created by the app), its name, platform and app version, and a push notification token so we can deliver notifications you have enabled.

Device integrity checks: to keep challenges fair, the app asks Apple (App Attest) or Google (Play Integrity) to confirm it is a genuine copy running on a genuine device. We store the result (passed, basic, failed or unavailable) and the date, not information about the rest of your device.

Your time zone, so that a challenge day starts and ends at your local midnight. If it changes shortly before you join a challenge, we note that for review.

Presence checks: during a challenge, Stint occasionally asks you to confirm you are still there (a tap, or a short code shown on your computer). We record when each check was issued and whether it was answered.

Purchases: if you subscribe to Stint Pro, Apple tells us the subscription’s status (active, expiry, renewal) so we can unlock Pro features. Apple handles the payment; we never see your payment details.

3. Stint on Your Computer and Browser

If you install Stint on a Mac or Windows computer, or the Stint browser extension, and link it to your account, it takes part in your focus sessions the same way your phone does.

What leaves your computer: for each minute of a session, the number of seconds in each category above; counts of input activity (how many key presses and pointer movements happened, and whether the input looked automated), never which keys you pressed or what you typed; identifiers for apps and websites only where they make up your own rules or a suggestion you send us (for example "docs.google.com" or a signed app identifier); and whether blocking is working on that device.

What never leaves your computer: window titles, full web addresses and page paths (other than paths in rules you write yourself), page content, keystrokes, screenshots, and the list of apps you run.

The browser extension reads the address of the site in your active tab on your device to decide whether it counts as work or should be blocked. Only the website's domain is ever used outside your device, as described above.

4. How We Use Your Information

To operate Stint: create and secure your account, run focus challenges, verify qualifying focus time, decide who qualifies, and process entry fees and payouts.

To keep challenges fair: focus verification, moderation of group chat (including acting on reports), and detection of attempts to game the system.

To communicate with you: sign-in codes, notifications you have enabled, and updates about the service.

To improve the product: aggregated usage analytics and crash reports.

We do not sell your personal information, we do not use it for advertising, and we do not use it to track you across other companies’ apps or websites.

5. Payments and Payouts

Entry fees are collected by our payment provider, Whop, through a secure checkout. Whop handles your payment details under its own privacy policy; Stint receives only confirmation that a seat was paid for and the amount.

Prize-pool payouts are reviewed manually by our team and sent outside the app. To send a payout we may need details such as your name and, where the law requires it, tax information. We keep records of payouts as long as financial and tax rules require.

6. Service Providers We Rely On

We share information only with providers who help us run Stint, and only as much as they need: Apple (Screen Time, App Attest, In-App Purchase, and push notifications), Google (Play Integrity, Google Play Billing and Firebase Cloud Messaging on Android), Whop (entry-fee payments), Mixpanel (app analytics), Cloudinary (profile photo storage), Hostinger (server and database hosting), Cloudflare and Vercel (website), Umami and Microsoft Clarity (website analytics), and email delivery providers for sign-in codes and updates.

Our team receives internal alerts about account activity — for example when someone signs up or a subscription changes — through a private, staff-only channel on a third-party messaging service. Those alerts are used to run the service, not for marketing.

We may also disclose information when required by law or to protect Stint, our users, or others.

7. Website Analytics

On trystintapp.com we use Umami, a privacy-first analytics service that counts visits without cookies or personal data, and Microsoft Clarity for aggregated heatmaps and session insights. Clarity data is governed by Microsoft’s privacy practices. The app itself uses neither.

8. Data Retention and Deletion

We keep your information while your account is active and for as long as needed to provide the service and meet legal obligations.

Detailed per-minute focus records (the categories and input counts above) are kept for 90 days after the challenges they were part of have settled, so results can be reviewed, and are then deleted. Daily totals are kept with your history.

You can delete your account at any time from Settings in the app. Deletion anonymises your account — your email, handle, and name are removed — and your profile photo is no longer displayed. Records we are required to keep (for example, payout and payment history) are retained in anonymised form for as long as the law requires.

If a payout is still owed to you, deletion is paused until it has been sent, so that we can still pay you.

9. Your Rights

Depending on where you live, you may have the right to access, correct, export, or delete your personal data, and to object to or restrict certain processing. To exercise these rights, contact us at the address below. Deleting your account from within the app is the fastest way to remove your data.

10. Children

Stint is for adults. You must be 18 or older to join a challenge with an entry fee, and we do not knowingly collect information from anyone under 18. If you believe a minor has created an account, contact us and we will remove it.

11. Changes to This Policy

If we make material changes, we will update the date at the top of this page and, where appropriate, notify you in the app or by email.
