Data Deletion Instructions
Last updated: October 26, 2026
This page explains how to ask Montra Joint Stock Company to delete data, including data received through Facebook, Messenger, Instagram, WhatsApp and Zalo Official Account.
1. If you messaged or commented on a hotel’s Page/OA
- Facebook / Instagram: go to Settings & privacy → Settings → Business Integrations, select Montra and click Remove.
- Zalo: unfollow the hotel’s Official Account.
- Then email dearmontra@gmail.com with the subject “Data deletion request”, including:
- the name of the hotel’s Facebook Page / Zalo OA you contacted;
- your Facebook/Zalo display name (and the phone number you gave the hotel, if any).
2. If you are a hotel using Montra
- Disconnect a channel: in Montra go to Settings → Connected channels and click Disconnect. The access token is deleted immediately and Montra stops receiving new data from that channel.
- Delete all data: an account owner (Boss role) emails dearmontra@gmail.com from the email registered with Montra, stating the business unit code.
3. What Montra does
- Acknowledges your request within 3 business days.
- Deletes the related data (messages, comments, profile information, user IDs, access tokens) within 30 days, including backups when they rotate.
- Data that the law requires us to retain (e.g. the hotel’s accounting records) is kept until the legal retention period ends, then deleted.
- Notifies you by email once deletion is complete.
