Privacy Policy

Zuno (“Zuno”, “we”, “us”) is an AI language partner available on Android and the web at heyzuno.app. Zuno AI is the controller of the personal data described in this policy.

This policy applies to the Zuno Android app, our website and any related services that link to it.

Information you give us

• Account details — your name, email address and profile photo, or the basic profile Google shares when you choose “Continue with Google”.
• Learning profile — the languages you practise, your level, accent, daily goal, focus and app preferences.
• Conversations — messages you type or speak, Zuno’s replies, corrections, translations and saved vocabulary.
• Files and links — photos, PDFs, documents and web links you add to a chat or topic.
• Schedules and reminders — practice times, repeat rules and reminder settings you create.
• Support and reports — messages you send us and chats you report.

Information collected automatically

• Device information — device model, Android version, app version, language, time zone and a push notification token.
• Usage and diagnostics — sessions started, features used, errors and performance data that help us keep Zuno reliable.

Zuno asks for microphone access only when you start speaking practice. You can deny or revoke it at any time in your phone’s settings and keep practising by typing.

• While a voice session is live, your audio is streamed over an encrypted connection to transcribe your speech and generate Zuno’s spoken reply.
• We store the text transcript of the conversation, so you can review it and pick up where you left off.
• We do not use your voice to identify you, build a voiceprint or for advertising.

• Provide the service — run Free Talk, Topics, Roleplays and voice sessions, and give corrections and translations.
• Personalise practice — adapt lessons to your level, goals, accent and teaching-style preferences.
• Send notifications you ask for — scheduled-practice reminders, “remind me to continue” and, if enabled, weekly summaries.
• Keep Zuno safe — prevent abuse, review reported chats and secure accounts.
• Improve Zuno — fix bugs and understand which features help learners, using aggregated or de-identified data where possible.

We process data because it is necessary to provide the service you asked for, with your consent (for example microphone and notifications), and for our legitimate interest in keeping Zuno secure and working well.

Zuno relies on trusted providers that process data on our behalf, under contracts that limit use to providing their service to us. We do not allow them to use your content to train their own models where that choice is available to us.

We do not sell or rent your personal data, and we do not share it for targeted advertising. We share it only:

• With the service providers listed above, to run Zuno.
• When you choose to — for example, by making a chat public with “Share · Public access”. Anyone with the link can view that chat until you switch it back to “Only me”.
• To comply with law — or to protect the rights, safety and property of our users and Zuno.
• As part of a business transfer — such as a merger, with notice to you.

• Account, chats, topics and files — kept while your account is active, or until you delete them.
• Deleted accounts — removed from our live systems immediately and from backups within 30 days.
• Unsent uploads — automatically deleted after a short period.
• Chat reports — kept for up to 12 months to investigate safety issues.

Depending on where you live, you may have the right to access, correct, download, delete or restrict the use of your personal data, and to object to processing or withdraw consent.

• Download your data — Settings → Account → Download my data. We email you a link to a copy.
• Edit your profile — Settings → Account.
• Notifications — Settings → Notifications, or your phone’s settings. Every email has an unsubscribe link.
• Microphone — revoke anytime in your phone’s settings.

You can also contact [email protected]. You have the right to complain to your local data protection authority.

You can delete your account and associated data at any time:

• In the app — Settings → Account → Delete account.
• On the web — heyzuno.app/delete-account, without needing the app installed.

Deletion removes your profile, chats, topics, roleplays, schedules, uploaded files and push tokens. It can’t be undone.

Zuno is not directed to children under 13 (or the minimum age in your country) and we do not knowingly collect their data. If you believe a child has given us personal data, contact us and we will delete it.

We protect data with encryption in transit (TLS), access controls, signed short-lived links for private files and least-privilege access for our team. No system is perfectly secure, so we also ask you to keep your email account secure.

Our providers may process data in countries other than yours, including the United States. Where required, we rely on safeguards such as the European Commission’s Standard Contractual Clauses.

We’ll update the date at the top when this policy changes. For significant changes we will notify you in the app or by email before they take effect.
