Your bicycle records

Bikes, odometer readings, components, installation periods, services, costs and preferences are stored locally on your device. The app does not upload those records or provide cloud sync. There is no app account, advertising SDK or behavioral analytics SDK.

Optional purchases

The free notebook does not initialize the purchase service. Checking prices, purchasing Pro, or restoring purchases connects to Google Play and RevenueCat. Those services process purchase history and status, transaction identifiers, an app-specific anonymous customer identifier, locale and currency, and technical request information such as platform, app version and IP address. Bicycle records are not sent to them. Google Play handles payment details; the app does not receive payment-card numbers.

Pro is a permanent purchase, not a subscription. The app caches purchase status for offline access and keeps pending-payment information to avoid repeating an uncertain checkout. Purchase-related data supports app functionality, purchase analytics, transaction handling and fraud prevention. We do not sell it or use it for advertising. See Google’s privacy policy and RevenueCat’s privacy policy.

Backups and deletion

JSON backups contain bicycle records and preferences, never purchase entitlements or reviewer access. You choose where to save exports and which copies to share. A destination service handles your exported file under its own terms. The app does not automatically upload exports.

Clearing app storage or uninstalling can remove local records. Keep an exported backup first. Files already exported remain where you saved them. Removing local data does not refund purchases or erase Google Play or RevenueCat transaction records. Those services may retain records needed for restores, refunds, fraud prevention or legal obligations.

Purchase-related data requests

Email pierdo.dev@gmail.com, name Spoke Ledger and describe your request. We may need enough purchase information to find the record and verify the request. Never send passwords or payment-card details. Records needed for transaction, restore or legal obligations may be retained for those purposes. Remove local bicycle records on your device as described above.

Contact and changes

Send privacy questions to pierdo.dev@gmail.com. Policy changes will show a new effective date and material changes will be reflected in app and store disclosures.
