Privacy policy

What OneHorizyn knows about you, why it needs it, who else handles it, and what you can ask us to do with it.

Last updated 16 October 2026 · Ascendus Private Limited

The short version
  • We collect little

    Your email address, your colleagues' addresses, your billing details and what you add about your hotels.

  • No advertising

    No advertising cookies, here or in the app. Google Analytics counts visits to this website. The app counts which of its pages each hotel opens, for us alone, with no outside tool.

  • Paid by invoice

    You pay our invoice from your bank. We keep the amount, the date and the invoice.

  • Ask, and we delete it

    Write to us to see, correct or delete what we hold about you.

What we collect about you, and why

Your email address
To sign you in: we email you a code or a link. If you set a password, our sign-in provider keeps it in scrambled form, and we never see it.
Your colleagues' email addresses
When you invite people to your group, so that they can sign in and so that you can see who has access and what each may do.
What you add about your hotels
The hotels you set up, the competitors and questions you confirm, your facts, notes and to-dos, and any files you upload. This is what the service works from.
Billing details
A business name, an email address for invoices and, if you give them, a phone number, a GST number and an address. We use them to make out and send invoices.
Payments
The amount, the date, the invoice it paid and the bank's reference. We never receive or keep a bank password.
That you agreed to these policies
When you create your account you tick a box to agree to the terms and conditions and this policy. We keep the date you did, and which version you agreed to.
Sign-in attempts
A daily count of sign-in emails and attempts against an email address and an IP address, kept to stop abuse.
Technical records
Our hosting provider keeps the usual server records, such as IP address and browser type, to run the service and keep it safe.
Errors
When a page, a button or a reading runs into an error, here or in the app, we keep a note of it: the page, the hotel that was open, what went wrong and where in our code, with email addresses, phone numbers, long text and keys taken out. Your browser sends us the errors it runs into on our pages in the same way. Each note is deleted once the error has not happened for 90 days.
Your chats with Ask OneHorizyn
The questions you ask Ask OneHorizyn about a hotel, and its answers, kept for you alone so that you can open a chat again on any device. Nobody else sees them in the app, and they are not shown when OneHorizyn's team looks at the app as you. What you say yes to in a chat, such as marking a to-do done or sending an email, and what came of it are kept with the chat and go with it; the record of an email sent stays with the others your mailbox sent. When you rate an answer "Helpful" or "Not helpful", the rating and the note you add to it are kept with the chat too, and go with it; we count how many answers are rated each way, and if you mark an answer "Not helpful", OneHorizyn's team may read that answer and your note, to make Ask OneHorizyn better. We delete each chat 12 months after its last question, or when you delete it.
Pages you open in the app
Which of the app's pages are opened for each hotel, each day, how often, and whether from a link in one of our emails. Each person is counted as a code made from their account, not by their name or email address, and nothing on the page is recorded. We use it to decide which pages to improve, and delete it after 13 months.
When you book a call
Your name, your email address, your hotel or group's name and how many hotels you have, and, if you give them, its website, a phone number, guests' email addresses and a note. We use them to hold the call and to follow up about OneHorizyn.
When you use the free check
The hotel's name, website and town you enter, and what the check found, so that we can see which hotels use it. We don't ask for your name or email address. To stop abuse, we keep a daily count of checks against a scrambled form of your connection's IP address.
03

What we collect about hotels

Most of what OneHorizyn holds is not about people at all. It is public information about hotels: prices on booking sites, ratings and reviews, search results, social posts, pages of the hotel's own website and screenshots of public booking pages.

Reviews are kept as their text, rating, date and the site they came from, with the reviewer's country and kind of trip where the site shows them, and without the reviewer's name. A review's text can still contain personal details its author chose to publish.

04

What we do not do

  • We do not sell or rent what we hold about you.
  • We do not use it for advertising, and we do not let advertisers track you here.
  • We do not use tools that follow you from one website to another. Google Analytics counts visits to this public website alone, with Google's advertising features and Google signals turned off.
05

Who else handles it

We use a small number of companies to run OneHorizyn. Each handles only what it needs for its job.

Supabase
Signing in, and the database where your account and your hotels' data are kept.
Vercel
Hosting: the servers that deliver this website and the app.
GitHub
Scheduled checks, such as the weekly screenshots of booking pages, run on its servers.
Google (Gmail)
Only if you connect your mailbox: Google sends the emails you press Send on, from your address.
OpenAI
Reads your hotel's reviews and drafts replies to them, and answers the questions typed into Ask OneHorizyn from what we collected about your hotel. It receives the reviews' text, which can include what their authors chose to say about themselves, and the questions you type.
Resend
Sends our emails, such as sign-in codes, the weekly summary and alerts. It receives your email address and what each email says.
Search and data services
To collect public data we send hotel names and search terms, never your personal details, to services such as DataForSEO and Google.
Google (Analytics)
Counts visits to this public website: the pages read, the country or city they were read from, the kind of device and the website that sent you. Not in the app, and not used for advertising.
Unsplash
The photographs on this website are loaded from its servers.
Cal.com
The calendar on the call page: the time you pick and what you type when you book go to Cal.com, which sends the invitation.
Google (Calendar and Meet)
Calls are held on Google Meet and kept in our Google Calendar, with the details you gave when you booked.

These companies may keep and handle data in countries other than yours. We also disclose information when the law requires it.

06

Cookies

OneHorizyn sets only the cookies it needs, and none is used for advertising. The app sets its cookies once you sign in. On the public website, Google Analytics sets two cookies to count visits; in the UK, the European Economic Area and Switzerland it sets none and counts visits without them.

Sign-in cookies
Keep you signed in. Set by our sign-in provider when you log in; their names begin with "sb-".
horizon_property
Remembers which hotel you were looking at.
horizon_open
Remembers, until you close the browser, that you opened a hotel from the list of all your hotels.
horizon_style
Remembers whether you chose the light or the dark look.
horizon_menu
Remembers whether you made the menu at the side smaller.
horizon_chats
Remembers how wide you made the list of chats in Ask OneHorizyn, or that you hid it.
horizon_mail_state
Lasts ten minutes while you connect your mailbox with Google, so that we know it is you coming back.
_ga and _ga_6L3X23SS48
Google Analytics, on the public website only: tell one visit from another, for up to two years. Not set in the UK, the European Economic Area or Switzerland.
Cal.com's calendar
The calendar on the call page is Cal.com's own, shown inside our page, and Cal.com may set cookies of its own there. Its privacy policy says which.
onehorizyn_call
Not a cookie: once you book a call, the day, time and Google Meet link of that call are kept in your browser until you close the tab, to show them on the page that confirms it. Never your name or email address.
07

The browser add-on

OneHorizyn has an add-on for the Chrome browser that helps a hotel reply to guest reviews on other sites. You choose whether to install it, and it does nothing until you open it.

  • It reads only the words you have highlighted on the page in front of you, and only when you open it. It does not read the rest of the page, your other tabs or your browsing.
  • It sends us those words, the name of the site they are on and the score you type in. We keep them with your hotel's other reviews, and use them to draft a reply.
  • Highlight the review alone. We do not ask for a guest's name and do not need it: if you highlight one with the review, it is kept as part of the words you sent.
  • It never posts anything. It puts the reply in the box you clicked in, and you press the site's own button.
  • It holds no password of yours. It is connected by a code made on your Reviews page; making a new code there stops the old one.
08

Sending from your own mailbox

You can connect the one mailbox your hotel writes from, a Gmail or Google Workspace address, in Settings. You choose whether to, and nothing is sent from it until you press Send on an email and confirm it, or say yes to sending it in Ask OneHorizyn after reading the whole of it there. Ask OneHorizyn can send, from that mailbox and only on a yes, one email at a time: one written for a to-do, such as to a booking site or your web team, or one to a company on Outreach.

  • Google gives us permission to send email as that address, and tells us which address it is. We do not ask to read, search, change or delete your email, and we cannot.
  • We send only the emails you press Send on, or say yes to in Ask OneHorizyn, one at a time, and no more than 40 from one mailbox a day, 10 of them at most from Ask OneHorizyn. From Ask OneHorizyn, only your hotel's own admins and editors can send from it: OneHorizyn's team never does there. We keep a record of each: to whom, its subject, when, who sent it and Gmail's reference for it, so that you can see what went.
  • The permission is kept encrypted, and only our servers use it. Disconnecting in Settings deletes it and gives it back to Google; you can also remove OneHorizyn from your Google account at any time.
  • The people you name as contacts at companies and booking sites (a name, a role and an email address) are kept with your hotel, to address the emails you send them.
  • OneHorizyn's use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements. We do not use it for advertising, we do not sell it, and we do not use it to train AI models.
09

How long we keep it

  • Your account and your hotels' data are kept for as long as your account is open.
  • The weekly screenshots of booking pages are kept for less time: none is kept longer than 3 months. The prices read from them are kept with the rest of your data.
  • Your chats with Ask OneHorizyn are kept for 12 months after a chat's last question, then deleted. You can delete one sooner, from the list of your chats.
  • What was collected about a competitor you take off, such as its prices, reviews and website, is kept for 30 days, so that it can be put back, and is deleted within the week after.
  • When the period paid for ends, the hotels' pages close and their data is kept, so that it is there if you return. Ask us and we delete it.
  • Records of payments and invoices are kept for as long as tax and accounting law requires.
10

What you can ask us to do

Write to hello@onehorizyn.com and we will, for what we hold about you:

  • show you what it is;
  • correct it;
  • delete it, apart from records the law requires us to keep;
  • give you a copy you can take elsewhere.

We answer within 30 days. If you are not satisfied with our answer, you can also complain to the data protection authority where you live.

11

Keeping it safe

Connections to OneHorizyn are encrypted. Each group's data is kept apart from every other group's, and inside a group each person sees only the hotels they have been given. No system is perfectly safe: if something goes wrong that affects you, we tell you.

12

Children

OneHorizyn is a service for businesses. It is not meant for children, and we do not knowingly collect information about them.
