Türkçe

Effective date: 20 October 2026 · Version 1.0

1. Introduction

Jettel İletişim Teknolojileri ve Yazılım Hizmetleri Sanayi Ticaret Limited Şirketi ("Jettel", "we", "us") values the privacy of its users. This Privacy Policy explains which personal data is processed when you use the Jettel mobile application available on Google Play and the App Store (the "App"), the purposes for which it is used, with whom it is shared, how long it is kept and your rights in relation to it.

This Policy applies to the App only. Use of the jettel.com.tr website is governed by a separate privacy policy.

By using the App you acknowledge that you have read this Policy.

2. Data Controller

The data controller under the Turkish Personal Data Protection Law No. 6698 ("KVKK") is:

Jettel İletişim Teknolojileri ve Yazılım Hizmetleri Sanayi Ticaret Limited Şirketi Platform Merter D Blok, No: 2-75, Abdurrahman Nafiz Gürman Mahallesi, Haldun Taner Sokak, 34160 Güngören / İstanbul, Türkiye E-mail: support@jettel.com.tr

3. About the App

Jettel is a business softphone that lets you make and receive calls with SIP (internet telephony) accounts. Accounts are not created in the App; your SIP service provider gives you your SIP account and you add it to the App. To allow an account to be used, the App verifies its licence through Jettel's servers.

Your SIP account and the calls you make with it are subject to the rules and privacy policy of the SIP service provider that gave you the account. Jettel is responsible for the data processed for the App's licence verification, device binding, notification and call diagnostics functions.

4. Information We Collect

The following information is processed so that the App can work.

Account information. The username, SIP domain and password of the SIP account you add to the App. Your password is sent to our servers to verify your account; our servers store only an irreversible digest of it, never the password itself. Your password is stored encrypted on your device.

Device and app information. Your device's manufacturer, brand, model and operating system version, and the App version. This information is used for compatibility, support and troubleshooting.

Installation and notification identifiers. The notification identifier (token) used to deliver incoming calls and changes to your account to your device, and the installation and binding identifiers created by the App. The notification identifier is stored encrypted on our servers.

Call diagnostics. When a call ends, technical information such as the call direction and outcome, error code, call identifier, call times, connection type and App version, so that we can detect and fix call problems. This information does not include the content of the conversation.

Call data. When you make or receive a call, the called and calling numbers, the technical information needed to set up the call, and the audio and video of the conversation are transmitted in real time to the other party through your SIP service provider. Jettel does not record your calls and has no access to their content.

Information processed only on your device. Your contacts, call history, profile photo and the QR code you scan to add an account are processed only on your device and are not sent to our servers.

Support file. If you choose to create and share a diagnostics file to get support, it is sent only to the person or app you select.

Information we do not collect. The App does not collect your advertising identifier, IMEI/IMSI, serial number, phone number, location, Wi-Fi network names or IP address. The App contains no advertising or analytics tools. Your passwords and access keys are never written to logs or crash reports.

5. Device Permissions

The App requests the following permissions to provide its functions. You can turn them off at any time in your device settings; the related feature will then not be available.

  • Microphone: transmitting your voice during calls.
  • Camera: adding an account with a QR code and video calls.
  • Contacts: showing your contacts by name and saving new contacts. Contact information never leaves your device.
  • Notifications and full-screen notifications: showing incoming calls.
  • Phone call management and foreground service: working correctly with the operating system during calls.
  • Network and Wi-Fi state: reconnecting your account when your connection changes.

6. How We Use Your Information

We use your personal data only for the following purposes:

  • verifying your SIP account and checking its licence;
  • enabling you to make and receive calls;
  • notifying your device of incoming calls and changes to your account;
  • detecting and fixing call problems and answering your support requests;
  • keeping the service secure and preventing misuse;
  • complying with our legal obligations.

Under Article 5 of the KVKK, your personal data is processed on the following legal grounds: the conclusion and performance of a contract for account verification, licensing, calls and notifications; our legitimate interest for call diagnostics and security records; and legal obligation for statutory retention duties.

We do not sell your data and do not use it for advertising.

7. Who We Share Your Information With

Your personal data is shared only to the extent necessary to provide the service, with:

  • Your SIP service provider: to carry your calls.
  • Google and Apple: to deliver incoming call and account notifications to your device. Only the identifiers needed for notifications are sent to these companies.
  • Competent authorities: where required by applicable law and upon a lawful request.

8. International Transfers

Our servers are located in Türkiye. The Google and Apple services used to deliver notifications run on these companies' infrastructure outside Türkiye; only the identifiers needed for notifications are transferred abroad for this purpose.

9. Retention Periods

We keep your personal data for as long as necessary for the purpose for which it is processed:

  • Call diagnostics: kept for 7 days and then deleted automatically.
  • Account and device binding records and the notification identifier: kept as long as the account is added to the App.
  • When you remove an account from the App: the account information, your password and the account data on your device are deleted, and your device binding, session and notification relationship on our servers are ended immediately. These ended records and security records are kept for 12 months for security and fraud prevention and then deleted.

Removing an account from the App does not delete your account with your SIP service provider.

10. Security

We take appropriate technical and organisational measures to protect your personal data against unauthorised access, loss and misuse. All communication between the App and our servers is encrypted; notification identifiers are stored encrypted on our servers, SIP passwords are stored only as an irreversible digest, and sensitive information is kept encrypted on your device. Only authorised personnel who need it for their duties can access the data.

Encryption of the audio and signalling of your calls depends on the configuration of your SIP service provider.

11. Your Rights

Under Article 11 of the KVKK you have the right to learn whether your personal data is processed, to request information about it, to learn the purpose of the processing and whether it is used accordingly, to know the third parties to whom it is transferred in Türkiye or abroad, to request its correction if it is incomplete or inaccurate, to request its deletion or destruction, to request that these actions be notified to the third parties to whom it was transferred, to object to a result to your detriment arising solely from automated analysis, and to claim compensation for damage caused by unlawful processing.

To exercise these rights, send your request to support@jettel.com.tr. We may need to verify your identity before handling your request. Requests are answered within 30 days at the latest. If you are not satisfied with our answer, you may lodge a complaint with the Turkish Personal Data Protection Board (Kişisel Verileri Koruma Kurulu).

12. Removing Your Account

To remove an account from the App, go to Settings → your account → Remove Account. To close or delete your SIP account itself, contact your SIP service provider. To request the deletion of your data on our servers, write to support@jettel.com.tr.

13. Children's Privacy

The App is intended for business users and is not directed at persons under 18. We do not knowingly process data of persons under 18.

14. Changes to This Policy

We may update this Policy from time to time. The current version is published on this page with its effective date. We will also announce significant changes in the App or on its store page.

This Policy is also published in Turkish; if the two versions differ, the Turkish version prevails.
