Privacy Policy — ThinkSolve101

Last updated: July 20, 2026

ThinkSolve101 ("we", "the app") is a problem-solving app (Logic Tree, Decision Matrix, Gap Analyzer) published by lepetit.hari on Google Play. This policy describes what data the app collects, how it's used, how it's shared, how long it's kept, and your rights. By installing and using ThinkSolve101, you agree to this policy.

ThinkSolve101 requires no account and has no backend server of its own — all content you create stays on your device. The app only uses a few standard Google services to operate (analytics, crash reporting, ads, billing).

1. Data We Collect

1.1. Data you create — stored on your device only

Everything you enter (Logic Tree problems, Decision Matrix entries, Gap Analyzer analyses, display name, and preferences) is stored locally on your device using shared_preferences. This data is never sent to any server and we cannot access it. Uninstalling the app or clearing its data in Android Settings permanently deletes all of this content.

1.2. Data collected automatically via third-party services

Data type	Service	Description
In-app interactions (screens opened, tools used)	Firebase Analytics	Anonymous usage statistics, not tied to your name or email
Crash & diagnostic logs (crash log, app version, device model)	Firebase Crashlytics	Anonymous crash reports so we can fix bugs
Device / advertising identifier (Advertising ID)	Google AdMob	Used to serve ads to users who haven't upgraded to Premium
Purchase status (purchased / active)	Google Play Billing	Only the entitlement status is received, to unlock Premium

We do not collect your name, email, phone number, GPS location, contacts, photos, files, or health data. We also do not build a personal profile of you.

2. How We Use Data

Operating & maintaining the app — serving ads (free users), processing Premium upgrades.
Improving the product — understanding which features are useful via anonymous statistics.
Bug fixing & stability — analyzing crash reports.

We do not use this data for any other purpose and we do not sell data to third parties.

3. Sharing Data With Third Parties

The automatically collected data in section 1.2 is processed by Google's services under their own policies. For Premium purchases, all payment information (card, balance, etc.) is handled directly by Google Play; ThinkSolve101 never sees or stores payment details, and only receives the purchase status.

4. Data Retention

Local data (section 1.1): kept until you uninstall the app or clear its data.
Firebase Analytics: kept under Google's default configuration (up to 14 months), then auto-deleted.
Crashlytics: crash reports are retained for up to about 90 days.
Advertising ID: managed by Google; you can reset or delete it anytime (see section 6).

5. Security

Data you create is kept in the app's private storage on your device and protected by Android's OS-level security mechanisms. Data sent to Google services is encrypted in transit (HTTPS). No method is completely secure, but we take reasonable measures to protect your information.

6. Your Rights

Delete local data: uninstall the app or clear its data via Android Settings → Apps → ThinkSolve101.
Turn off/limit personalized ads: Android Settings → Privacy → Ads (reset/delete your Advertising ID), or upgrade to Premium to remove ads entirely.
GDPR rights (if you're in the EEA): access, rectify, delete, restrict, or object to processing, and data portability. Contact the email in section 9 to exercise these.
CCPA rights (if you're in California): we do not sell your personal data.
Request deletion of Analytics/Crashlytics data or other questions: contact the email in section 9.

7. Children

ThinkSolve101 is not directed at children under 13 and we do not knowingly collect data from them. If you believe your child has provided data to us, please contact us so we can address it.

8. Policy Changes

We may update this policy as the app evolves (for example, adding cloud sync in a future version). Any changes will be posted on this page with a new "Last updated" date.
