At Sparqor Technologies, your privacy is a core principle — not an afterthought. This policy explains clearly and plainly what data Tono collects, why we collect it, and how we keep it safe. By using Tono, you agree to the practices described here.
Account information. When you create an account, we collect your email address and, optionally, a display name, so you can sign in and sync your progress across devices.
Voice and training data. Tono uses your device's microphone exclusively during active practice sessions and vocal scans. Audio is processed entirely on your device to measure characteristics such as pitch (fundamental frequency), resonance, formants, stability, and clarity. We store only the resulting numeric scores and your session history (e.g. session type, duration, streaks, XP). We never upload or store raw audio recordings on our servers.
Usage and preference data. We store your training goals, daily practice targets, reminder preferences, vocal range profile, and subscription or plan status to personalise your experience and help you track progress over time.
Device permissions. The App requests:
You may revoke either permission at any time in your device Settings; doing so may limit certain App features.
We do not use your data to serve advertisements or build advertising profiles.
We share data with the following trusted service provider solely to operate the App:
We may also disclose information if required to do so by law, court order, or to protect the rights, safety, or property of Sparqor Technologies, our users, or the public.
We never share your data with advertisers, data brokers, or any third parties for their own commercial purposes.
Your account and progress data is stored on Supabase infrastructure with row-level security (RLS) enforced at the database level, ensuring only your authenticated session can access your records. Connections are encrypted in transit using TLS.
Some data is cached locally on your device so core features work even when offline. Local data is protected by your device's own security mechanisms (e.g. iOS Secure Enclave, Android Keystore).
While we apply industry-standard safeguards, no system is completely immune to security risks. We encourage you to keep your app and device software up to date.
We retain your account and progress data for as long as your account remains active, or as needed to provide the service.
You may request complete deletion of your account and all associated data at any time by contacting us at sparqor@gmail.com. We will process deletion requests within 30 days and confirm once complete.
Note: Some anonymised, aggregated usage statistics may be retained for analytics purposes, but these cannot be linked back to you.
Tono is not directed at, and is not intended for use by, children under the age of 13. We do not knowingly collect personal information from children under 13. If you believe we have inadvertently collected information from a child, please contact us immediately at sparqor@gmail.com and we will promptly delete it.
We may update this Privacy Policy from time to time to reflect changes in the App, our business practices, or applicable law. When we make material changes, we will update the "Last updated" date at the top of this page. For significant changes, we may also notify you through the App or via email.
Continued use of Tono after changes are posted constitutes your acceptance of the updated policy.
