Vonophone provides internet-based calling services. This Privacy Policy explains what information we collect, how we use it, and your choices. By using Vonophone, you agree to this policy.
We do not record or store call audio by default. If we add call recording, it will only occur when you enable it. You are responsible for obtaining any required consent. Recordings can be deleted at any time.
When you use the Vonophone mobile app, we may collect:
To protect our service and users from abuse, we collect a stable device identifier:
We transmit a hashed form of this identifier to our servers when you register, log in, open the app, or request a calling token. We use it to detect banned or abusive devices, prevent duplicate fraudulent accounts, and enforce account restrictions. We store hashed fingerprints in our database (Supabase) linked to your account.
Legal basis: legitimate interests (security and fraud prevention). You may object to this processing by contacting [email protected]; objection may limit your ability to use the service.
We do not use device fingerprints for advertising or sell them to third parties.
