Privacy Policy

Last updated: June 24, 2026

SummaryPolara is a local-first practice journal. It does not require an account or sign-in, and your practice data is not uploaded to Polara-operated servers.

English

This Privacy Policy explains how Polara ("the App", "we", "us") handles information when you use the Polara pole practice journal app.

Information the App Handles

  • Practice data, including trick progress, training sessions, planned sessions, duration, notes, studio names, custom tricks, featured moves, onboarding answers, persona quiz results, and related preferences.
  • Profile data, including your locally entered display name, avatar image selected from your photo library, app language, achievements, and progress state.
  • Purchase information provided through StoreKit, including product identifiers and verified subscription or lifetime purchase status used to unlock paid features and restore purchases.
  • JSON backup files you choose to export or import. Backups may include practice data, profile data, custom tricks, app preferences, and onboarding data.
  • Calendar data, if you enable calendar features. The App may create, update, delete, or read Polara training events in Apple Calendar.
  • Photo library data, if you choose an avatar or custom trick image. The selected image is copied to app-owned local storage and is not uploaded by Polara.
  • Technical and diagnostic information that Apple or the operating system may process as part of App Store distribution, purchases, and platform services under Apple's policies and your device settings.

How We Use Information

Polara uses information to provide its practice, profile, recommendation, onboarding, purchase, backup, and optional calendar features; save progress and preferences locally; verify paid access; restore purchases; and maintain App reliability.

Local Storage

Polara stores App data locally using device storage and the App's document directory. This includes practice sessions, trick progress, custom tricks, studio names, onboarding answers, language preferences, local profile data, managed images, and JSON backup files.

Deleting the App or clearing local App data may permanently delete this information unless you exported a backup first.

No Account or Sign-In

Polara does not require an account, username, password, email address, or Sign in with Apple. Your local profile is not a cloud account and is not used to identify you across devices.

Purchases and Subscriptions

Polara may offer paid features through Apple in-app purchases. Apple processes payments and purchase records. The App uses StoreKit to display products, request purchases, verify current entitlements, unlock paid features, manage subscriptions, and restore purchases.

Polara does not operate a purchase server and does not receive your full payment card number. Deleting local App data does not cancel an Apple subscription. Subscriptions must be managed through your Apple account.

Photos

If you choose to set an avatar or add an image to a custom trick, Polara asks for photo library permission. Selected images are copied to app-owned local storage and are not uploaded by Polara.

Calendar

If you choose to use calendar sync, Polara asks for calendar permission. The App may create a "Polara" calendar and add, update, delete, or read Polara training events for sync and import features. Calendar access is optional.

Backups and Sharing

If you export a JSON backup, Polara creates a file on your device and opens the system share sheet. You choose where to send or store that file. Once shared with another app or service, that third party's privacy practices apply. Backup files may contain personal practice information, so keep them private.

Platform Services

Polara relies on Apple platform services for App Store distribution and purchases, StoreKit, device permissions, Photos, Calendar, the system share sheet, and platform diagnostics. Apple's handling of information is governed by Apple's privacy policies and your Apple account and device settings.

Expo and React Native provide software components used to build and run the App. Polara does not use those frameworks as a production account, analytics, advertising, or cloud-storage service.

Analytics, Advertising, and Tracking

Polara does not include third-party advertising SDKs, third-party analytics, or cross-app tracking for advertising. Polara does not sell your personal information.

Data Retention and Deletion

Locally stored data remains on your device until you delete it, clear local App data, delete the App, or overwrite it by importing a backup. Purchase records may be retained by Apple according to Apple's policies and legal obligations.

Your Choices

  • Decline or change optional Photos and Calendar permissions.
  • Export a JSON backup before deleting the App or clearing its data.
  • Delete local App data from the App's Settings screen.
  • Contact us at polaraapp@gmail.com with privacy questions or requests.

Children's Privacy

Polara is not directed to children under 13. We do not knowingly collect personal information from children under 13.

Security

We use reasonable technical measures appropriate for a local-first mobile app, including app-owned device storage. No method of storage or transmission is completely secure. You are responsible for protecting your device passcode, Apple account, and exported backup files.

International Users

Information handled by Apple platform services may be processed in countries or regions where Apple operates. That processing is governed by Apple's privacy policies and applicable law.

Changes to This Policy

We may update this Privacy Policy from time to time. If we make material changes, we will update the "Last updated" date and provide additional notice where required.
