Privacy Policy
Last updated: September 27, 2025
Our Commitment
SpeedProof respects your privacy. Your location and speed data stays on your device. We don't sell your information, and we only collect what's necessary to provide our service.
Information We Collect
Location and Speed Data
SpeedProof collects GPS location data and speed information only when you're using the app and have granted location permissions. This includes:
- GPS coordinates (latitude and longitude)
- Speed measurements from your device's GPS
- Timestamps for each data point
- Location accuracy measurements
Device Information
We may collect basic device information to ensure the app functions properly:
- Device model and operating system version
- App version and settings preferences
- Crash logs and performance data (anonymized)
How We Use Your Information
Primary Purpose
Your location and speed data is used exclusively to:
- Track your speed while driving
- Generate tamper-proof evidence for potential traffic disputes
- Create exportable reports in various formats (PDF, CSV, JSON, GPX)
Local Processing Only
All speed and location processing happens locally on your device. We use cryptographic hashing and digital signatures to ensure data integrity, but this processing occurs entirely within the app.
Data Storage and Retention
Local Storage
Your speed and location data is stored locally on your device. We only retain the last 2 minutes of any driving session, automatically deleting older data to protect your privacy.
No Cloud Storage
SpeedProof does not store your location or speed data on our servers or in the cloud. Your driving data never leaves your device unless you explicitly choose to export it.
Automatic Deletion
Speed tracking data is automatically deleted from your device except for the most recent 2-minute session, which you can manually delete at any time through the app settings.
Data Sharing
We Don't Sell Your Data
We never sell, rent, or trade your personal information to third parties. Your location and speed data belongs to you.
Service Partners
We may share minimal, necessary information with service partners to provide core app functionality:
- App store analytics (anonymized usage statistics)
- Crash reporting services (anonymized technical data)
- Customer support platforms (only when you contact us)
Your Rights and Controls
Location Permissions
You can revoke location permissions at any time through your device settings. Without location access, SpeedProof cannot function, but you maintain complete control.
Data Export and Deletion
You can export your speed data at any time in multiple formats, and you can delete all stored session data through the app settings or by uninstalling the app.
Security Measures
Encryption and Digital Signatures
All speed and location data is encrypted on your device using industry-standard encryption methods. We use ECDSA signatures stored in your device's Secure Enclave to ensure data integrity and prevent tampering.
Children's Privacy
SpeedProof is not intended for use by children under 16. We do not knowingly collect personal information from children under 16.
Changes to This Policy
We may update this privacy policy from time to time. We will notify you of any material changes through the app or by posting the updated policy on our website.

Privacy by Design
Remember: SpeedProof is designed with privacy by default. The less data we have, the less we can be compelled to share. Your driving data belongs to you, and we've built our system to keep it that way.
