Costr Privacy Policy

Effective Date: 14 November 2025
Publisher: Bilal Sevinc

1. Introduction

Costr is a subscription-tracking iOS application that operates entirely on the user’s device. This policy explains how information is handled. The app does not collect, transmit, or store information on external servers.

2. Data Collection

  • Costr does not collect, store, transmit, or process personal data.
  • No user accounts, emails, names, device identifiers, IP addresses, analytics, or behavioral data are collected.
  • The app has no authentication, internet requirement, or remote data access.

3. Local Data Storage

  • All subscription information is stored locally on the user’s device.
  • There is no cloud storage, external backup, or server-side database.
  • The developer never has access to user data.

4. Payments and Subscriptions

  • Optional subscription plans unlock full functionality.
  • Apple’s App Store handles all billing operations.
  • Costr and the publisher do not collect or store any payment information.

5. Third-Party Access and Sharing

  • Costr does not share, sell, disclose, or allow access to data because nothing is stored externally.
  • No third-party analytics, advertising SDKs, crash reporting tools, or tracking services are used.

6. User Rights

  • All data remains local and under the user’s control.
  • Users may delete data through in-app settings.
  • Uninstalling the app removes all locally stored data.

7. Security

  • Data never leaves the device and benefits from iOS sandboxing.
  • There is no network transmission.
  • Additional encryption or remote security layers are unnecessary due to the absence of server communication.

8. Data Retention

  • Data stays on the device until the user deletes it or removes the app.
  • Nothing remains after deletion or uninstallation.

9. Legal Compliance

  • Because Costr does not collect, store, or process personal data, requirements under GDPR, CCPA, and similar privacy laws do not apply.
  • The app complies with these regulations by virtue of non-collection and non-processing of personal information.

10. Policy Updates

  • This policy may be updated.
  • The latest version will be available on the publicly accessible privacy-policy page.
  • No notification mechanism is implemented.
