Privacy Policy
Last updated: 17 June 2026
We never record or store your voice. When you use the pitch and range features, your microphone is analysed live on your device, in your browser. The audio is never recorded, uploaded or saved — only numeric results (such as a pitch-accuracy score or your detected note range) are stored so you can track progress.
Who we are
This service ("Vocal Workout of the Day") is operated by Zangger Vocal Art AB, Sweden (the "data controller"). For any privacy question, contact us at hello@zangger.se or via our contact page.
What we collect
- Your name and email address (when you create an account).
- Your vocal register (e.g. male/female voice type) to tailor the exercises.
- Training history — which workouts you have completed and on what dates.
- Numeric voice results — pitch-accuracy scores and your detected vocal range (note values). No audio.
- Subscription status. Card payments are handled entirely by Stripe — we never see or store your card details.
How we use it
- To deliver the service and personalise your daily workout and progress.
- To manage your subscription and billing through Stripe.
- To send essential transactional emails (account, payment, reminders you opt into).
We do not sell your personal data, and we do not use it for third-party advertising.
Service providers
We use a small number of trusted providers to run the service: Supabase (database and authentication), Stripe (payments), and Vercel (hosting). Audio reference files are served from cloud storage. These providers may process data outside your country; where required, transfers rely on appropriate safeguards such as the EU Standard Contractual Clauses.
Cookies
We use only the cookies needed to keep you securely signed in. We do not use advertising or cross-site tracking cookies.
Keeping and deleting your data
We keep your data for as long as your account is active. You can permanently delete your account at any time from Account → Delete account. Deleting your account immediately and permanently removes your profile, training history and voice results from our database, and cancels any active subscription. You can also email us to request deletion.
Your rights
Wherever you live, you can ask us to access, correct, export or delete your personal data, and (in the EU/EEA, UK and similar regimes) object to or restrict certain processing. To exercise any right, email hello@zangger.se. If you are in the EU/EEA you also have the right to complain to your local data protection authority.
Children
The service is not directed to children under 13 (or the minimum age required in your country). We do not knowingly collect data from them.
Changes
We may update this policy from time to time. Material changes will be reflected by the "last updated" date above.
