Rowberry privacy policy
Last updated October 18, 2026. This policy covers the Android app Rowberry: Knitting Row Counter (com.tinyfair.rowberry) published by Tinyfair on Google Play.
The short version
The app works on your phone. We do not have accounts or servers, we do not track how you use the app, and we never receive your projects, patterns or personal details. The only data that leaves your phone goes to Google: for ads, for purchases, and a crash report if the app crashes, as described below.
Data that stays on your phone
- Projects and counts
- Saved only in a database on your phone the moment you tap. They are never sent to us. There is no account.
- Patterns
- PDFs you open are copied into the app's own storage on your phone and never uploaded.
- Backups
- A backup file is written only where you choose to save it. We never receive it.
- Purchases and trial reminder
- Handled by Google Play; we never see your payment details. The trial reminder is scheduled on your phone by Android.
Ads (Google AdMob)
The free version shows ads from Google AdMob. To show and measure ads, Google may collect your device's advertising ID, IP address, and information about ad interactions and app crashes. In the European Economic Area, the United Kingdom and Switzerland the app asks for your consent first, and you can change it later under Settings, Privacy choices. You can reset or delete your advertising ID in your Android settings. See how Google uses information from apps that use its services. Buying Pro removes all ads.
Crash reports (Firebase Crashlytics)
If the app crashes or hits a serious error, it sends a crash report to Firebase Crashlytics, a Google service that helps us find and fix the bug. A report contains the error and where it happened in the code, the app version, the device model, the Android version, and a random installation ID that is not linked to you, your Google account or your advertising ID. It never contains your projects, counts, notes or patterns. Reports are kept for 90 days. See Firebase privacy and security.
Purchases (Google Play)
Pro is sold through Google Play Billing as a yearly or monthly subscription (with a free trial for new subscribers on the yearly plan) or as a one-time lifetime purchase. You can cancel a subscription anytime in Google Play. We do not see your payment details; Google Play tells the app only whether Pro is active.
Permissions
Notifications, only to remind you before a free trial ends. Files are chosen with the Android file picker, so no storage permission is needed. No location, contacts, camera or microphone access. Internet is used for ads, purchases and crash reports.
Children
The app is not directed at children under 13 and we do not knowingly collect information from them.
Your choices and deleting data
Everything the app stores is on your phone: delete it inside the app or uninstall the app to remove it. For ad data, use your Android advertising ID settings or the Privacy choices option in the app.
Changes and contact
If this policy changes, the new version will be posted on this page with a new date. Questions: support@tinyfair.my.id.
