Privacy Policy
WattLog.pro ("we", "us", or "our") operates the wattlog.pro website, the WattLog.pro macOS application, and the WattLog.pro Smart Trainer iOS application (collectively, the "Service"). This policy explains what data we collect, how we use it, and your rights regarding it.
1. Data we collect
- Account data — your email address, chosen display name, and password (stored as a salted hash).
- Athlete profile data — name, age, weight, sex (all optional except name), and avatar colour.
- Training data — power (watts), heart rate (bpm), cadence (RPM), and elapsed time recorded during each session, plus derived metrics.
- Device data — the Bluetooth device name and type of your smart trainer and heart rate monitor. We do not collect serial numbers or persistent hardware identifiers.
- Usage events — anonymous, aggregated events such as "session started". These contain no personal identifiers.
We do not collect location data or payment card details (handled entirely by our payment processor).
2. How we use your data
- To provide and personalise the Service (power zones, FTP, Performance Management Chart).
- To store your session history so it is available across devices.
- To send transactional emails (account confirmation, password reset). We do not send marketing email without your explicit consent.
We never sell your data, share it with advertisers, or use health and fitness data to train third-party AI models.
3. Data storage and security
Your data is stored on servers in the EU (AWS eu-central-1). We use HTTPS for all data in transit and encrypt sensitive fields at rest.
4. Data retention
We retain your data for as long as your account is active. You can delete your account at any time; this permanently removes all associated personal data within 30 days.
5. Your rights (GDPR)
- Access — request a copy of the personal data we hold about you.
- Rectification — ask us to correct inaccurate data.
- Erasure — ask us to delete your data.
- Portability — export all your training data as TCX or FIT files.
To exercise any of these rights, email contact@wattlog.pro.
6. Cookies
The Service uses a single session cookie to keep you logged in. We do not use tracking or advertising cookies.
7. Children
The Service is not directed at children under 16. We do not knowingly collect data from children.
