Privacy Policy

This policy explains what data the Buddy Talk app collects, why it collects it, and how you can delete it. The app is published by Zoran Taskovic, Belgrade, Serbia. Contact for any privacy questions: buddy-talk@ztek.app.

What data we collect

• Account data. When you sign in with a Google or Apple account, we receive your email address, name and the account identifier from that service. We never see your Google or Apple password.
• Voice. While you talk, audio from the microphone is streamed in real time so Buddy can answer. We don't store audio recordings. The microphone is used only while the conversation screen is open.
• Conversation transcript. We store a transcript of what you say or type and what Buddy replies. This is how you see your conversation history in the app.
• Notes about you. At the end of a longer conversation, a short summary is created (e.g. your name, language, how you like to be addressed). Buddy uses it to remember you in the next conversation. We also remember the language you speak.
• Subscription. From Google Play we receive a purchase token, the subscription status and the billing period dates. We never receive payment details (card number and the like).
• Usage. For each reply we record the technical amount of processing, so we can track the monthly usage limit.

Why we use it

Only to make the app work: to answer what you say, show your history, remember you between conversations and check whether your subscription is active. We don't sell data, don't show ads and don't use data to track you across other apps.

Who we share data with

• OpenAI processes the voice and text of conversations to generate Buddy's replies, as well as summaries and language detection. Under OpenAI's API policies, this data is not used to train their models.
• Google (Google Play and Google Sign-In) and Apple (Sign in with Apple) handle sign-in and subscriptions, under their own privacy policies.
• The servers running the app and the database are located in Finland (EU), with Hetzner Online GmbH.

How long we keep data

We keep all your data for as long as your account exists. When you delete your account in the app, it is deleted immediately and permanently. When you request deletion by email, we delete it within 30 days.

Deleting your account and data

In the app: Account → Delete account. Your account, conversation history, notes, saved language, subscription records and usage data are deleted immediately and cannot be restored.

Without the app: send an email to buddy-talk@ztek.app saying you want your account deleted, and include your username or, if you signed in with Google or Apple, the email address of that account. Before deleting it, we may ask you to confirm that the account is yours. We will delete the same data within 30 days.

You cancel your subscription separately, in Google Play, because we can't cancel it for you. Deleting your account does not cancel it.

Your rights

You have the right to request access to the data we hold about you, to have it corrected or deleted, and to file a complaint with a data protection authority. In Serbia, that is the Commissioner for Information of Public Importance and Personal Data Protection.

Children

Buddy Talk is not intended for anyone under 18 years of age, and we do not knowingly collect their data.

Changes

If we change this policy, we will update the date at the top of this page. We will let you know about important changes in the app.
