1. Data Collection

We collect the following information to provide and secure our SIP service:

  • Account Information: Your email address and the country you select when registering. We do not ask for your name or a billing address.
  • Payment Data: Your card or wallet details are entered directly into Stripe's own payment fields and never reach our systems. We receive only the confirmation that a payment succeeded, together with the amount and a transaction reference.
  • Technical SIP Data: IP addresses used for registration, device type, and port numbers.
  • Call Detail Records (CDRs): Source number, destination number, call duration, timestamp, and call quality metrics.
  • Voicemail: If someone leaves you a voicemail, the recording and the caller's number are stored so that you can listen to the message.

Note: We do not record or store the audio content of your phone calls. Voicemail is the one exception — those messages are recorded by design, because that is what the feature does.

2. How We Use Your Data

We process your personal data for the following purposes:

  • To authenticate your SIP dialer and route phone calls.
  • To process prepaid transactions and manage account balances.
  • To detect, prevent, and mitigate fraud, hacking attempts, or abuse.
  • To comply with legal obligations (e.g., lawful interception requests by authorities).

3. Data Retention

  • CDRs: Kept for billing and fraud prevention purposes, typically retained for a period of six (6) to twelve (12) months, depending on statutory telecommunication laws.
  • Voicemail: Voicemail recordings are kept for thirty (30) days and are then deleted automatically. You will not receive a separate reminder before a message expires, so download anything you want to keep.
  • Account, Payment and Support Data: Retained as long as your account is active, and afterwards for as long as we are required to keep it — in particular to meet accounting, tax and other statutory retention obligations.

4. Data Sharing

We do not sell your data and we do not share it for advertising. Beyond the service providers listed in the next section, information is shared only with:

  • Telecommunications providers / network operators: To connect your calls, the number you dial and the number you call from may be passed to the network operators that carry the call. These operators may be located in different countries, depending on the destination.
  • Payment providers: To process your prepaid deposits.
  • Law enforcement agencies: If required by a valid legal subpoena or court order.

5. Service Providers

We rely on the following providers to operate the service. Each one processes only the data it needs for its purpose, and only on our instructions:

  • Supabase: Account registration, login and session handling. Processes your email address, user ID, login and session data, and the country you selected.
  • Stripe: Payment processing. Handles your card or wallet details directly; your balance is credited once Stripe confirms the payment to us.
  • Resend: Transactional email — account confirmation, password reset, contact form, voicemail notifications and system messages. Processes your email address, the message content, and delivery metadata.
  • Cloudflare: DNS, email routing, security and performance. Processes connection data such as your IP address, and email routing metadata.
  • Hosting: The website and the calling platform run on servers provided by Hetzner in Germany, operated by Impact Trading & Consulting GmbH. Deployments are managed with Dokploy, which runs on that same infrastructure.

International transfers: some of these providers are companies outside Switzerland and the EU/EEA, or may process data outside those regions. Where that is the case, the transfer takes place on the basis of the safeguards required by applicable data protection law. We use no analytics, advertising or tracking services, and we do not build profiles of our users.

6. Your Rights

You have the right to ask us what data we hold about you, to have it corrected if it is wrong, to have it deleted, to receive a copy in a portable format, and to object to or restrict certain processing. Exercising these rights is free of charge and will not disadvantage you.

To make a request, write to support@original-voice.ch. We may need to verify your identity before we act, so that nobody else can obtain your data by pretending to be you. Some data must be retained even after a deletion request where the law requires it — if that applies, we will tell you which data and why. You also have the right to lodge a complaint with your national data protection authority.

7. Security

We implement industry-standard TLS encryption for SIP signaling (SIPS) and SRTP for audio where supported. However, no method of transmission over the internet is 100% secure.
