Pixelcraft Labs ("we", "us", or "our") operates the AlgoScroll mobile application (the "App"). This page informs you of our policies regarding the collection, use, and disclosure of personal data when you use our App.
When you sign in with Google, we receive your name, email address, and profile photo from your Google account. This information is used to personalize your experience within the App (e.g., displaying your name and photo on your profile).
Your practice progress, bookmarks, streak counts, challenge history, and settings are stored locally on your device.
AlgoScroll offers optional sign-in via Google. You may also use the App without signing in by choosing "Continue as Learner." If you sign in with Google, your authentication session is managed by Firebase Authentication (operated by Google). Your name and profile photo are stored locally on your device for display purposes.
We use Firebase Analytics to understand general usage patterns such as which features are used and session duration. This data is aggregated and anonymous — we do not track individual behavior, build personal profiles, or sell data to third parties.
We use Firebase Remote Config to manage app settings and feature availability. This service does not collect personal information — it delivers configuration values to the App based on general criteria (e.g., app version).
AlgoScroll offers optional Pro subscriptions and a one-time lifetime purchase through Google Play Billing. When you make a purchase:
Payment is processed entirely by Google Play. We do not collect or store your payment information.
Google may collect data as part of the purchase process, subject to Google's own Privacy Policy.
Your Pro status is verified through Google Play and stored locally on your device.
The App integrates the following third-party services, all operated by Google:
Google Play Billing — for processing purchases
Firebase Authentication — for sign-in with Google
Firebase Analytics — for anonymous usage metrics
Firebase Remote Config — for app configuration delivery
These services are subject to Google's Privacy Policy (https://policies.google.com/privacy).
Local data (progress, bookmarks, settings): stored on your device until you uninstall the App or clear App data.
Authentication data (Firebase): retained until you delete your account or sign out.
Analytics data: retained by Firebase in aggregated, anonymous form per Google's data retention policies.
You can delete your account at any time from Profile → Danger Zone → Delete Account. This removes your authentication data from Firebase. Local data can be cleared by uninstalling the App or clearing App data from your device settings.
AlgoScroll is intended for users 18 years of age and older. We do not knowingly collect any information from children under 13.
We may update this Privacy Policy from time to time. We will notify you of any changes by updating the "Last updated" date at the top of this page. We encourage you to review this Privacy Policy periodically.
