1. Who We Are
Chordoo is operated by Louis-Frédéric Fortier ("we", "us", "our"). We are the data controller responsible for your personal data collected through www.chordoo.com (the "Service").
For any privacy-related questions, you can contact us at: loufi.officiel@gmail.com
2. Data We Collect
Chordoo has no accounts and no payments. We do not ask for your name, email address, or any payment details.
Saved Progressions (on your device only)
Progressions you save to your library are stored in your browser's localStorage. They never leave your device and are not sent to our servers. Share links contain the chords, key, mode, and genre of a progression in the URL itself, and are only seen by the people you choose to send them to.
Analytics Data
We collect anonymized usage events (e.g., feature interactions) through PostHog, which processes data on EU servers (eu.i.posthog.com). We do not track individual browsing behavior across other websites.
Local Storage
Besides your library, we use localStorage to remember small preferences, such as whether a notice has been shown. This data stays on your device.
3. Why We Process Your Data (Legal Basis)
Under the EU General Data Protection Regulation (GDPR), we process analytics data based on our legitimate interest (Art. 6(1)(f) GDPR) in understanding how the Service is used and improving it through anonymized analytics.
4. Third-Party Processors
We share analytics data with the following processor, bound by a data processing agreement:
| Provider | Purpose | Data Location |
|---|---|---|
| PostHog | Product analytics | EU |
5. Data Retention
- Analytics data: Retained per PostHog's default retention policies (typically 90 days for raw events).
- Your library and preferences: Stay in your browser until you delete them or clear your browser data.
- Former accounts: Chordoo previously offered optional accounts. All account data and progressions stored on our servers have been deleted.
6. Your Rights (GDPR)
As an EU/EEA resident, you have the right to:
- Access your personal data and obtain a copy
- Rectify inaccurate or incomplete data
- Erase your personal data ("right to be forgotten")
- Restrict processing of your data
- Port your data to another service in a machine-readable format
- Object to processing based on legitimate interest
- Lodge a complaint with your local data protection authority
To exercise any of these rights, contact us at loufi.officiel@gmail.com. We will respond within 30 days.
7. Cookies & Tracking
Chordoo does not use tracking cookies. We use browser localStorage for essential functionality only (your saved library and small preferences such as whether a notice has been displayed). These are not shared with third parties.
Our analytics provider (PostHog) operates on EU servers and does not use cross-site tracking cookies.
8. Children's Privacy
Chordoo is not directed at children under 16. We do not knowingly collect personal data from children under 16. If you believe we have inadvertently collected such data, please contact us and we will delete it promptly.
9. Security
We implement appropriate technical and organizational measures to protect your data, including:
- Encrypted connections (HTTPS/TLS) for all communications
- Keeping your saved progressions on your device instead of on our servers
10. Changes to This Policy
We may update this Privacy Policy from time to time. We will notify you of any material changes by updating the "Last updated" date at the top of this page. We encourage you to review this page periodically.
