Mikolaj Piech, operating Trailo (“we”), is the data controller for personal data processed through trailoapp.com and the Trailo apps. Contact: support@trailoapp.com.
What we collect
Depending on how you use Trailo, we may process:
- Account data: email, password hash, name, profile photo, language preference, optional onboarding answers
- Trip data: plans, messages, uploads, collaborators, tickets, and traveler details you add
- Group poll responses if you use a shared poll link without an account
- Payment status and purchase history (card details are handled by Stripe, not us)
- Booking details you submit when booking flights or hotels in the app
- Approximate location if you allow it, or inferred from IP during planning chat
- Session cookies, a locale cookie, device storage, server logs, and AI usage metadata
Why we use it
We use this data to provide and run the service, process payments, send account and invite emails, prevent abuse, and comply with law. Legal bases: contract (providing Trailo), legitimate interests (security and operations), and legal obligation where applicable. We do not sell your data or use advertising trackers.
AI features send your messages, trip data, and uploads to xAI for planning and editing. That provider may also use web search. See our Terms regarding AI output.
Who we share it with
We use processors including:
- Supabase — hosting, auth, database, storage
- Stripe — payments
- xAI — AI features
- Google — sign-in, if you choose it
- LiteAPI — bookings, if you use them
- Map, geocoding, hosting, and infrastructure providers needed to run the app
Some providers are outside the EEA (including the US). Where required, transfers use appropriate safeguards such as Standard Contractual Clauses.
Retention
Account and trip data are kept until you delete them or your account. Payment records are kept as required for tax and disputes. To delete your account, email support@trailoapp.com.
Your rights
Under the GDPR you may request access, correction, deletion, restriction, portability, or object to certain processing. Contact support@trailoapp.com. You may also complain to the Polish data protection authority (UODO) at uodo.gov.pl.
