Privacy Policy

Last updated: 31 July 2026

This policy explains what Amigurumi Buddy (“the app”) collects, why, and what control you have. It describes the app as it actually behaves — if the app changes, this page changes with it.

The short version

• You can use the app without an account. The pattern library, your saved patterns and your round-by-round progress all work offline, on your device.
• Signing in is optional. It exists so imported patterns can be backed up and follow you to another device.
• We do not sell your data, we do not share it with advertisers, and there is no advertising in the app.

What is stored on your device only

These never leave your phone unless you sign in and use the backup feature:

• Which patterns you saved to My patterns, and when you last opened each one.
• Your round-by-round progress on every pattern.
• Your theme and language preference.
• The skill level and categories you picked during onboarding.
• Patterns you imported from a PDF, including the extracted text.

Deleting the app deletes all of this.

What we collect if you create an account

Signing in is optional, and you can sign in with an email address, with Apple, or with Google. In each case we receive:

• A user ID issued by Firebase Authentication.
• Your email address, when the sign-in method provides one. If you use Sign in with Apple and choose Hide My Email, we only ever see Apple’s relay address — we cannot see your real one.
• Your name, only if Apple or Google supplies it at first sign-in.

Authentication is handled by Google Firebase Authentication. We do not receive or store your password for Apple or Google sign-in.

Patterns you import

If you import a pattern PDF while signed in, the original PDF file is uploaded to Firebase Storage in a folder that only your account can read or write. It is stored so you can restore your library on a new device. We do not read, index or share these files, and nobody else can access them.

If you are not signed in, imported patterns stay on your device and nothing is uploaded.

If a pattern cannot be read on-device, the extracted text may be sent to our own server to be structured into steps. Only the text is sent, never the file, and it is not retained after the response is returned.

Analytics

We use Firebase Analytics to understand which parts of the app are used, so we know what to improve. Analytics events deliberately carry no personal information — no names, no email addresses, no pattern contents, no free text. They record things like which screen was opened and whether an action succeeded.

Subscriptions

Subscriptions are processed by Apple, and managed through RevenueCat, which tells the app whether your subscription is active. We never see your payment card or billing details — Apple does not share them with us. RevenueCat receives an anonymous identifier and your purchase history for this app.

Who your data is shared with

Only the service providers that make the app work:

Provider	What they process	Why
Google Firebase	Account, imported PDFs, analytics events	Sign-in, backup, analytics
RevenueCat	Purchase records, anonymous ID	Subscription status
Apple	Payment and subscription	Processing your purchase

We do not sell personal data, and we do not share it for advertising.

Your choices

• Use the app without an account — then nothing is collected at all.
• Delete your account and data: email the address below and we will delete your account, your uploaded PDFs and any associated records. We complete these requests within 30 days.
• Delete local data: remove the app from your device.
• Depending on where you live you may have rights to access, correct, export or erase your data, and to object to processing. Contact us and we will help.

Children

The app is not directed at children under 13 and we do not knowingly collect data from them. If you believe a child has given us personal data, contact us and we will delete it.

Patterns

The patterns bundled with the app are free patterns published by their designers. If you are a designer and want your pattern removed, contact us and we will remove it.

Changes

If this policy changes materially we will update the date at the top and, where the change affects you, tell you in the app.
