Privacy Policy

1. Overview

This Privacy Policy explains what information LinkyGrid collects, how we use it, and your choices. LinkyGrid is a daily logic puzzle game with optional account features planned and game data powered by Supabase.

2. Information We Collect

Depending on how you use the game, we may collect:

• Account data: email address and authentication identifiers from Supabase if account features are available and you choose to use them.
• OAuth sign-in data: basic account identifiers from third-party sign-in providers if those options are available and you choose them.
• Gameplay data: daily puzzle attempts, completion status, puzzle domain, attempts used, duration, and anonymous guest identifiers.
• Stats data: streaks, counts, averages, and daily aggregate puzzle statistics if stats features are available.
• Feedback submissions: message, optional email, page path, and whether you were signed in if feedback features are available.
• Technical metadata: timezone for daily puzzle resolution and related metadata.
• Usage analytics: website analytics events collected via Vercel Analytics.

3. Local Storage and Similar Technologies

LinkyGrid stores some information in your browser, including:

• A guest daily identity ID used to associate anonymous daily puzzle progress before sign-in.
• Saved daily progress for a puzzle date and puzzle key.
• UI preferences such as theme and difficulty-start hints.
• Session/auth persistence handled by the Supabase client if account features are available.

If you clear browser storage, these local values may be removed.

4. How We Use Information

• Provide core game features and daily puzzle functionality.
• Save and restore your progress and stats.
• Link guest progress to your account after sign-in if account features are available.
• Improve gameplay balance, reliability, and product quality.
• Respond to feedback and support requests.
• Monitor aggregate usage trends and performance.

5. How We Share Information

We do not sell your personal information. We share data with service providers only as needed to operate LinkyGrid, including:

• Supabase for authentication, database, and backend functions.
• Vercel Analytics for usage analytics.
• OAuth identity providers when you use social sign-in, if those options are available.

We may also disclose information if required by law or to protect the security and integrity of the service.

6. Data Retention

We keep data for as long as reasonably necessary to provide and improve LinkyGrid, comply with legal obligations, and resolve disputes. Local browser storage persists until removed by you or overwritten by the app.

7. Your Choices

• You can play without creating an account.
• You can choose not to submit optional feedback or optional email contact details.
• You can clear browser storage to remove local app data.
• You can stop using social sign-in providers if those options are available.

8. Security

We use reasonable measures designed to protect information, but no system is completely secure. Please use a secure device and browser when accessing LinkyGrid.

9. Children's Privacy

LinkyGrid is not directed to children under 13, and we do not knowingly collect personal information from children under 13.

10. International Users

Your information may be processed in countries other than your own, depending on where our service providers operate.

11. Changes to This Policy

We may update this Privacy Policy from time to time. When we make material changes, we will update the effective date on this page.
