Nutkin Privacy Policy
Nutkin is a to-do app with a gentle idle game attached. This policy describes what information the app handles, and — mostly — what it deliberately does not.
The short version
- What you type stays on your device. Task titles, steps, notes and tags are never transmitted to us — not in backups, not in analytics.
- Your colony is backed up. The app creates an anonymous account automatically so your game progress (acorns, buildings, achievements) can be restored. You may optionally link Apple or Google so it survives a lost phone.
- We collect a small amount of anonymous usage and crash data to fix bugs and improve the app. It never includes anything you type.
- We do not sell data, show ads, or use third-party advertising or tracking SDKs.
Data stored on your device only
Everything you create in Nutkin — task titles and steps, tags, your pet's name and appearance, streaks, acorn balances, buildings, achievements, journal-style history — is stored locally on your device. If you delete the app, this data is deleted with it.
Your account and what is backed up
So your colony is not lost with your phone, the app creates an anonymous account the first time it runs. This account is a random identifier — creating it requires no email, no phone number, and no information about you.
What we store: a snapshot of your game state — acorn balance, buildings owned, achievements earned, and similar progress figures — with our infrastructure provider (Supabase, servers in the United States), solely to restore your colony.
What we never store: the contents of your to-do list. Task titles, steps, notes and tags stay on your device and are not part of the backup.
Linking an account (optional). You may link Sign in with Apple or Google so your colony can be restored on a new device. If you do, we receive the email address that provider gives us — with Sign in with Apple you may choose Apple's private relay address, in which case we never see your real one. We use it only to identify your account.
Deleting it. Settings → Delete account & data removes your account and everything stored on our servers. Your local data stays on your phone until you delete the app.
Anonymous analytics (PostHog)
To understand which features help people (for example: how many users finish onboarding, or whether daily streaks are used), the app sends event names and counts — such as "task_completed" or "den_bought" — to PostHog, an analytics service.
- Events are associated with a random identifier, not your name, email, phone number, or any advertising ID.
- Events never include the content you type: no task titles, no step text, no pet names. We collect shapes, not content.
- We do not use this data for advertising and do not share it with data brokers.
- Analytics does not track you across other companies' apps or websites.
Crash reports (Sentry)
If the app crashes or malfunctions, a crash report is sent to Sentry, an error-monitoring service. A report contains technical information: the error and stack trace, app version, device model, operating system version, and the sequence of screens/actions leading up to the crash. Crash reports are configured to exclude personally identifying information and never include your task content.
Purchases
If you subscribe to Nutkin Plus (when available), payment is processed entirely by Apple. We never see or store your payment details. Subscription entitlement is verified via App Store receipts.
Notifications
Reminders and streak notifications are scheduled locally on your device. We do not operate a push-notification server in this version.
Children
Nutkin is a general-audience productivity app and is not directed at children under 13. We do not knowingly collect personal information from children under 13.
Your choices and rights
- Delete your data: delete the app; local data is removed with it.
- Analytics: the analytics identifier is random and not linked to your identity. If you would like the events associated with your device's identifier deleted, contact us at support@nutkinapp.com and we will pass the deletion request to our processors.
- Depending on where you live (e.g., EU/EEA, UK, California), you may have additional rights — access, correction, deletion, portability, and the right to lodge a complaint with a supervisory authority. Contact us to exercise them; we do not discriminate for doing so.
