Privacy Policy
Overview
Lahnova turns a prompt or a photo into a short AI video. This policy says what data that takes, who processes it, and how you delete it. We do not sell your data, we do not show ads, and we do not track you across other companies' apps or websites.
No account
Lahnova has no sign-up and no login. We never ask for your name or phone number. The app is identified by a random install ID created on your device, not by who you are.
Information we collect
Content you submit
- The prompts you write and the photos you choose from your photo library
- The videos, images and audio Lahnova generates for you, kept so you can reopen and save them
Purchases
Lahnova offers auto-renewing subscriptions that add video credits. Payment is handled entirely by Apple; we never see your card details. We receive purchase records (product, price, country, renewal or refund status) from Apple through our subscription provider RevenueCat, linked to the random install ID, not your name.
Usage and diagnostics
To understand how the app is used and fix problems, we collect usage data (such as screens viewed, buttons tapped, and whether actions succeed or fail) and diagnostic data (such as crash reports, freezes and performance). This data is collected with a random app ID, is not used for advertising, is not sold, and is not linked with data from other companies' apps or websites. Location lookup from your IP address is switched off, and your prompts and photos are never sent to these tools.
Session recordings are only made if you turn on "Help improve Lahnova" in Settings. Text, photos and camera views are hidden on your device before anything is sent, and recordings are deleted after 30 days. You can turn analytics and recordings off at any time in Settings.
Feedback you send
If you use "Report a problem" or "Suggest an idea", we receive your message, any screenshot you choose to attach, the app name and version, your iOS version and device model, and your email address only if you enter one. We use this only to answer you and fix or improve the app, and keep it for up to 24 months. If you report a generated video as harmful, we receive the report and the video it refers to.
Email updates (optional)
We collect your email address only if you tick "Send me updates, customer-only discounts and news about your other apps". The box is never pre-ticked and is never required to buy anything. We record the wording you agreed to, the date and time, the app and your language setting as proof of consent. Every email has a one-click unsubscribe link, and you can also email us to be removed. We don't sell or share your email address.
Services that process your data
- Lahnova backend (hosted by Vibecode): stores your projects and coordinates generation.
- kie.ai: runs the AI models that generate your video from your prompt and photo.
- Google Gemini API: safety-checks prompts and photos before generation.
- RevenueCat: subscription and purchase records from Apple.
- PostHog (hosted in the European Union): product analytics and, only if you opt in, session recordings.
- Sentry: crash and error reporting.
- Apple: App Store, payments and app delivery, under Apple's own privacy policy.
These providers act for us, only to deliver the features above. We do not use your content to train AI models.
Deleting your data
There is no account to close: your data is tied to this install of the app, and you can delete it yourself at any time. In the app, open Settings → Remove my videos and data. This immediately deletes your projects, prompts, photos and generated videos from our database and resets the install ID, so nothing remaining can be linked back to you. Copies of media files held by our storage provider are cleared within 30 days. You can also email support@smbdmtechnologies.com and we will delete your data within 30 days.
Deleting the app from your device removes the data stored on the device. Videos you saved to your photo library stay there until you delete them. Subscriptions are managed by Apple: deleting the app does not cancel one (see Terms of Use).
Your rights
Depending on where you live, you may have the right to access, correct, export or delete your personal data, or to object to some processing. Email support@smbdmtechnologies.com and we will respond within the time your local law requires.
Children
Lahnova is not directed at children under 13, and we do not knowingly collect data from children. If you believe a child has sent us data, contact us and we will delete it.
Security
Data is encrypted in transit (HTTPS/TLS). No system is perfectly secure, but we take reasonable measures to protect the data we hold.
Changes
If we change this policy we will update the effective date above, and for significant changes we will tell you in the app before they take effect.
