Privacy Policy
Lexxio (“we,” “us”) built this app so you can read your way into a new language. This policy explains what data we collect on this website and in the Lexxio app, why we collect it, and the choices you have.
Information we collect
On this website
- Waitlist email address. If you join the waitlist, we store the email you give us and use it to send you a confirmation and, later, a launch notification.
- Standard server logs. Our hosting provider (Vercel) automatically logs request metadata such as IP address and user agent for security and abuse prevention. We don’t use this data for advertising.
We don’t run analytics or advertising trackers on this site, and we don’t use cookies beyond what’s strictly necessary to serve the page.
In the Lexxio app
- Your library, reading progress, and vocabulary. This is stored locally on your device. We don’t upload your books, highlights, or notes to our servers.
- Account information. If you create an account (for subscriptions or cross-device sync), we store your email and authentication details with our backend provider (Supabase).
- Translation requests. When you use cloud translation or read-aloud, the relevant text is sent to our translation/text-to-speech provider to generate a result. We cache results to avoid sending the same text twice.
- Payment information. Subscriptions and one-time purchases are processed by Stripe, Apple, or Google Play, depending on where you subscribe. We never see or store your card details.
How we use information
We use the data above to operate the waitlist, run your account and subscription, generate translations and audio you request, and keep the service secure and reliable. We do not sell your personal data, and we do not use it for third-party advertising.
Third parties we work with
Upstash (waitlist storage), Resend (transactional email), Supabase (accounts), Stripe, Apple, and Google Play (payments), and our translation/TTS providers process data strictly to provide the service on our behalf, under their own security and privacy commitments.
Data retention
We keep waitlist emails until launch or until you ask us to remove them. Account data is kept while your account is active and deleted within a reasonable period after you request account deletion.
Your rights
You can ask us to access, correct, export, or delete your personal data at any time by emailing hello@lexxio.ai. If you joined the waitlist and want out, every email includes an unsubscribe link, or you can just email us.
Children’s privacy
Lexxio is not directed at children under 13, and we don’t knowingly collect personal data from them.
Changes to this policy
We’ll update this page if our practices change and update the date below. Material changes will be announced on this site or by email to registered users.
