Data processing addendum
How HostyFlow handles the personal information your restaurant puts into HostyFlow. Version 2026-09-29.
Last updated September 29, 2026
The parties
This addendum sets out how HostyFlow handles the personal information your restaurant puts into HostyFlow.
Your restaurant decides what information about your guests and your team goes into HostyFlow, and what it is used for.
HostyFlow handles that information only to run HostyFlow for you, and only as your settings and your team's actions in the Workstation direct. Those settings and actions are your instructions.
The information and why
What HostyFlow handles for you, and the only reasons it does.
Names, phone numbers, email addresses, bookings, party sizes, notes, allergies, occasions, visits, texts, emails, call recordings and transcripts, voicemails, faxes and payment records. Never card numbers.
Names, email addresses, phone numbers, roles, schedules, sign-ins and the changes each person makes.
To take and manage bookings, run your waitlist and floor, answer your calls and messages, send the texts and emails you set up, take payments into your account and keep your records. HostyFlow does not sell this information or use it to advertise.
Your guests' details stay with your restaurant. They reach another restaurant only when a guest signs in to HostyFlow and chooses to share them.
Subprocessors
The companies HostyFlow uses to run the service.
Every company that handles your restaurant's information for HostyFlow is named at hostyflow.com/trust/subprocessors, with what it does, what it touches and where. The page shows the date it last changed.
Security
The measures in place today.
Each restaurant's bookings, guests and floor live in storage of its own. No other restaurant can open them.
Every page, screen and connection to HostyFlow uses HTTPS.
Each person signs in with a one-time code sent to their own email or mobile number. Their role decides what they can open, and HostyFlow checks the role on its servers.
Every change in the Workstation is recorded with the person's name and the time.
Guests type card numbers only on the payment company's page. HostyFlow never receives them.
HostyFlow's team opens your account only through a support session that lasts at most an hour, needs a written reason and is recorded.
Breaches, requests and removal
What HostyFlow does when something goes wrong or someone asks.
If HostyFlow learns that someone reached your restaurant's information without permission, HostyFlow emails your account owner within 72 hours with what happened, what information was involved and what HostyFlow is doing about it.
If a guest asks you to remove their details, use Remove on their guest card in the Workstation, or send them to hostyflow.com/privacy. Either way their details are removed from use right away. If a guest asks to see their details, forward it to privacy@hostyflow.com.
Removed details leave every screen, list and message at once, and no more texts or emails go to that guest. A sealed copy is kept for at least three years for legal and dispute needs, and it is never used for anything else. hostyflow.com/trust/retention shows how long each kind of record is kept.
