Privacy Policy

Last updated: April 19, 2026

1. Introduction

FirewoodIdentifier ("the App") is developed by Bulpara Inc. This privacy policy explains how the App collects, uses, and protects your data when you use our AI-powered firewood identification service.

2. Information We Collect

When you use the App, you submit photos of firewood for AI analysis. These photos are transmitted securely to our servers for processing. We also collect:

• Scan results (species, BTU rating, seasoning signals, safety verdict)
• Scan history stored locally on your device via iCloud Key-Value Store
• Anonymous identifiers for rate limiting and abuse prevention
• Diagnostic and crash data to improve the app

3. How We Use Your Data

Your firewood photos are sent to our backend API, which forwards them to a third-party AI model (Replicate) for species identification. We use your data solely to provide the firewood identification service.

4. Camera Access

The App requests camera access to capture photos of firewood for analysis. You may also select existing photos from your gallery. Photos are transmitted to our servers exclusively for AI scanning and are not used for any other purpose.

5. Data Storage & Retention

• Uploaded photos are temporarily stored on Cloudflare R2 for the duration of the scan and deleted within 24 hours
• Scan results (species, BTU, etc.) are stored locally on your device via SwiftData — we do not keep a copy on our servers
• No account or personal information (name, email, etc.) is required to use the App

6. Advertising (Free Tier)

The free version of the App displays advertisements provided by Google AdMob. AdMob may collect device identifiers, IP addresses, and usage data in accordance with Google's privacy policy. Premium subscribers see zero advertisements and no ad-related data collection occurs. For details, see Google AdMob Privacy.

7. App Tracking Transparency (ATT)

On first launch (after onboarding), non-premium users see Apple's standard tracking permission prompt. You may accept or deny. Denying does not limit app functionality — only ad personalization.

8. Subscription Data

Premium subscriptions are processed through Apple App Store. We verify subscription status via signed StoreKit transactions to unlock premium features but do not receive, process, or store any payment information. Subscription management is handled entirely by Apple.

9. Third-Party Services

• Replicate AI (firewood identification model processing)
• Cloudflare R2 (temporary secure image storage)
• Google AdMob (free tier only — Privacy Policy)
• Apple App Store (subscription management — Privacy Policy)

10. Data Security

• All data transmission uses HTTPS encryption
• API authentication via secure API keys
• Rate limiting to prevent abuse (100 requests per minute per device)
• Temporary images stored on Cloudflare R2 with access controls and automatic deletion

11. Data Deletion

You can delete individual scans from the History screen at any time. Uninstalling the App removes all locally stored data. Server-side images are auto-deleted within 24 hours; to request immediate deletion of any residual data, contact us at the email below.

12. Children's Privacy

The App is rated 4+ and does not target children under 13 for advertising. We do not knowingly collect personal information from children under 13.

13. Changes to This Policy

We may update this privacy policy from time to time. Changes will be reflected in the "Last Updated" date above. Continued use of the App after changes constitutes acceptance of the updated policy.
