Hotel data. Guest names, phone numbers, ID types, stays, payments and staff records are stored so your hotel can operate. Each hotel's data is isolated at the database level — no other hotel, and no one outside TRENX Digital's operations team, can read it.

Guests. Guests who scan a room QR share only what they type (name, phone, order, request, review). They can ask the hotel to delete it. We do not track guests across hotels or sell guest data.

Messaging and payments. WhatsApp messages are sent through Meta's Cloud API from the hotel's own number; payments are processed by Razorpay. We store references, not card numbers.

Where. Data is hosted on Supabase and Vercel infrastructure with encrypted connections and daily backups. We keep it while your account is active and for 90 days after, unless you ask for earlier deletion.

Cookies. Only a sign-in cookie and a cookie remembering which hotel this device belongs to. No advertising trackers on the app; basic analytics on this website only.
