Privacy Policy
How we treat the data you trust us with.
Prostay is the operating system that hotels, hostels and short-stay groups run their daily business on. This policy explains, in plain English, what data we collect, why we collect it and what control you have over it.

In short: we collect the data we need to run your account and the platform itself. We never sell personal data. We never use your operational data to train models that benefit anyone other than your property. You can export or delete your data at any time.
Section 01
Who we are
Prostay Limited is the data controller for the prostay.com marketing site, the Prostay product and any data your team submits when contacting us.
Address: Suite C, Level 7, World Trust Tower, 50 Stanley Street, Central, Hong Kong.
Contact: office@prostay.com.
When you operate Prostay on behalf of a property, we act as a processor for the guest data you upload (reservations, folios, payments, messaging). The property remains the controller of that data.
Section 02
What we collect
We split data into three categories so it is obvious which one you are looking at.
Account data
- Name, work email and role, when you create an account or request a demo.
- Property name, country and basic operational profile (room count, brand affiliation).
- Billing details processed by our PCI-compliant payment partners. We never store full card numbers.
Operational data
- Reservations, room assignments, folio postings, housekeeping status, payments and refunds you create inside Prostay.
- Guest profile data (name, contact details, ID document references) that you choose to capture.
- Messaging history with guests through channels you have connected (WhatsApp, Booking.com, Expedia and email).
Telemetry
- Device and browser metadata, IP address and the URLs you visited on prostay.com.
- Errors and performance traces from the product, scrubbed of any guest data before they leave your tenant.
Section 03
Why we collect it
We only collect data we need to do one of four things.
- Run your account. Authenticate users, provision properties, render the product, take payment.
- Operate the platform safely. Detect fraud, recover from incidents, audit access.
- Improve Prostay. Aggregate, anonymous usage signals tell us which features need work.
- Communicate with you. Account notifications, security alerts and the occasional product update if you opt in.
Section 05
How long we keep it
- Active customer data is kept for as long as your subscription is active.
- Closed-account data is kept for 90 days, then deleted unless a longer retention period is required by law (typically 7 years for financial records).
- Marketing and prospect data is kept for up to 24 months from your last interaction.
Section 06
Your rights
Depending on where you live, you have the right to access, correct, export or delete your personal data. You can also object to certain processing or withdraw consent.
Submit any of these requests to office@prostay.com. We respond within 30 days, faster on most days.
For account data inside the product, you can self-serve most of these rights from Settings → Privacy.
Section 07
How we protect it
- Data is encrypted in transit (TLS 1.2 or higher) and at rest (AES-256).
- Access to production systems is limited to a small on-call rotation, behind SSO and hardware-backed MFA.
- We run continuous vulnerability scanning, third-party penetration tests and ship security patches within published SLAs.
You can find our trust posture at discover-prostay and request a copy of our most recent security questionnaire from your account team.
Section 08
Changes to this policy
We update this policy when our practices change. Material changes are communicated to admins inside the product at least 30 days before they take effect.
A real human reviews every legal request.
