Privacy Policy

Last updated: March 22, 2026

Pavel Kulitski ("we", "our", "us") built the Skill Decay Tracker app as a Freemium application. This page informs visitors about our policies with the collection, use, and disclosure of personal information if anyone decides to use our service.

Information We Collect

Skill Decay Tracker is built with a privacy-first approach and collects minimal data:

AI Challenge Generation

When you practice skills, the app sends your skill name, category, and difficulty level to an AI provider to generate challenges. If you use the built-in AI (no personal key), requests are routed through our proxy server. The proxy server:

If you use your own API key, requests go directly to the AI provider (Anthropic, OpenAI, or Google) under their respective privacy policies.

Data Storage

All your skill data, practice history, and personal settings are stored locally on your device. We do not have access to this data. If you delete the app, all local data is permanently removed.

Third-Party Services

The app uses the following third-party services, each governed by their own privacy policy:

Children's Privacy

Skill Decay Tracker is not directed at children under the age of 13. We do not knowingly collect personal information from children under 13. If you believe your child has provided us with personal information, please contact us so we can take appropriate action.

Data Deletion

You can delete all your data at any time from within the app via Settings → Delete All Data. Uninstalling the app also removes all locally stored data. To request deletion of any analytics data associated with your device, contact us at the email below.

Changes to This Policy

We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated revision date. Continued use of the app after changes constitutes acceptance of the updated policy.
