Privacy Policy

Vennla (“Vennla,” “we,” “us”) is a language-learning app. This policy explains what information we collect, how we use it, and the choices you have. By using Vennla you agree to this policy.

Information we collect

• Account information. We use Clerk, our authentication provider, to manage sign-in. This includes your email address and name, and — if you sign in with Apple, Google, or Microsoft — basic profile information from that provider.
• Learning data. Your study activity: the words you learn, review history, spaced-repetition state, streaks, and progress statistics.
• Content you provide. Vocabulary you add, texts and documents (including PDFs) you upload to build custom corpora, and the messages you send to our AI conversation and tutoring features.
• Payment information. If you subscribe to Pro, payments are handled by Stripe (web) or the app stores (mobile). We do not store your full card details.
• Usage and device data. Basic technical data (such as app version and general interaction data) needed to operate and improve the service.

How we use your information

• Provide, personalize, and improve the learning experience;
• Generate AI-assisted content — translations, grammar, conversation, and pronunciation;
• Process subscriptions and payments;
• Communicate service-related information;
• Maintain security and prevent abuse.

AI processing and third-party services

To provide our features we share limited data with service providers (“sub-processors”) who process it on our behalf:

• Clerk — authentication and account management.
• Neon — database hosting for your account and learning data.
• Vercel — application hosting and file storage (Vercel Blob) for texts you upload.
• Anthropic (Claude) — powers AI tutoring, conversation, and vocabulary features. The messages and text you submit to those features are sent to Anthropic to generate responses.
• Google (Gemini) — powers text-to-speech and pronunciation. Text submitted for audio is sent to Google.
• Stripe — subscription and payment processing.

These providers are required to protect your data and use it only to provide their services to us. We do not sell your personal information.

Data retention and deletion

We keep your data for as long as your account is active. You can permanently delete your account and associated learning data at any time — on the web, open the account menu in the sidebar and choose Delete account; on iOS and Android, use Settings → Delete account. Some records may persist briefly in backups, and in third-party providers according to their own retention policies.

Your rights

Depending on where you live, you may have rights to access, correct, export, or delete your personal information. You can exercise most of these directly in the app, or by contacting us at the address below.

Children

Vennla is not directed to children under 13 (or the minimum age required in your country), and we do not knowingly collect their personal information.

Security

We use industry-standard measures — encryption in transit, access controls, and reputable infrastructure providers — to protect your data. No method of transmission or storage is completely secure.

International transfers

Your information may be processed in countries other than your own, including the United States. Where required, we rely on appropriate safeguards for these transfers.

Changes to this policy

We may update this policy from time to time. Material changes are reflected by updating the “Last updated” date above.
