Privacy statement
Roomalert is a Telegram bot that alerts you when a room or studio comes up in Amsterdam or Utrecht, and that lets you place a room yourself. This page says what Roomalert keeps about you, why, for how long, and how to erase all of it.
In short
- Roomalert keeps only what it needs to send your alerts, show your room and pass on a conversation.
- Searchers and advertisers never see each other's Telegram name, phone number or mail address. If you want to take it further, you write your details in a message yourself.
/verwijderin the bot erases everything at once.- This website sets no cookies, does not track you and loads nothing from other parties.
Who is responsible
Roomalert, [name, legal form, address and Chamber of Commerce number of the controller]. Questions about your data go to info@roomalert.nl.
If you are looking for a room
To be able to alert you, Roomalert keeps:
- the number of your Telegram chat with the bot, your language and whether your alerts are on or paused;
- your search profile: the city, your maximum rent, the smallest size, from when you are looking, and your two preferences (only indefinite or longer than three months, registration required);
- your first name and a short introduction, if you give them. They go along when you respond to a room;
- your mail address, if you also want alerts by mail, and whether you have confirmed it;
- which rooms you were alerted about, when, and which button you used. That way you do not get the same room twice.
Your profile is kept until you erase it. The history of your alerts is erased after 90 days.
If you place a room
Of a room you place, Roomalert keeps your answers (city, room or studio, rent, size, neighbourhood, dates, registration), the text you write, and for each photo the reference Telegram returns. Roomalert does not keep the photo files themselves; they stay with Telegram. If you give a street and postcode, they are never shown: they only serve to avoid placing the same room twice.
Roomalert also keeps the state the room is in, when you submitted it, and the outcome of the review, as a code and without a note. For the bot's limits (five rooms a week at most, a limited number of responses and messages a day) it counts how often you submit or send something.
Searchers get the facts, your text and your photos in their alert. This website shows the facts only: room or studio, neighbourhood, rent, size, available from, rental length and registration. A room that the bot sends with a warning is not shown on the website.
Conversations through the bot
When a searcher responds to a room, the bot passes the messages on. The advertiser sees the searcher's first name and short introduction. The bot never shows a Telegram name, phone number or mail address of one person to the other.
The messages of a conversation are kept while it is open and until 30 days after it was closed. Then they are erased. They are kept so that a report of abuse can be judged: when either party presses "Meld misbruik" (report abuse), the owner of Roomalert gets to see the conversation.
How long things are kept
| What | How long |
|---|---|
| Your search profile, your language, your mail address | until you use /verwijder |
| History of your alerts | 90 days |
| A room you started placing but did not finish | 24 hours after your last answer |
| A placed room | visible for 14 days, and with an extension at most three times 14 days more |
| A rejected room you do not submit again | 30 days after the rejection |
| A room that was rented, removed or has expired | 90 days after that; the references to the photos are erased as soon as the room is erased |
| The outcomes of the reviews of your rooms (one code each) | as long as the room is kept, and otherwise 90 days |
| Messages of a conversation | until 30 days after the conversation was closed |
| Facts and link of a room on another site | the room leaves the list when the source no longer shows it, or 30 days after it was first seen; 90 days after that it is erased |
| A block that outlives an erased account | twelve months after the block (see below) |
Anthropic's language model
Roomalert uses a language model made by Anthropic (Claude) for two things:
- A room you place is reviewed before it goes out. Its text, the facts you entered and the photos go to the model for that. The model gives a verdict: approve, reject, or put it before the owner. In case of doubt the owner decides, not the model.
- Advertisements on other sites are read to take two things from them: the rental length and whether registration is possible. The text of such an advertisement is read for that only and is never stored by Roomalert.
Your profile, your mail address and the number of your Telegram chat do not go to the model. [To be confirmed by the owner: the terms agreed with Anthropic on processing and retention, and the country in which the processing takes place.]
Rooms on other sites
Of a room that is listed on another site, Roomalert keeps facts only (city, neighbourhood, rent, size, dates, rental length, registration) and the link to the advertisement. No text, no photos and no name or contact details of the advertiser.
Blocking
Someone who abuses the bot can be blocked by the owner and can then no longer place or respond. With a block, the moment and a short reason are kept.
When someone who is blocked erases their account, one thing stays: a hash of their Telegram user id, made with a secret key, for twelve months after the block. In a conversation with the bot that id is the same number as that of the Telegram chat. That way the block still holds if that person comes back. Nothing else of that person is kept: no name, no messages, no reason. Without the key the id cannot be worked out from the hash. [For the lawyer to weigh: the hash remains personal data for as long as the key exists.]
When someone erases their account while a report of abuse against them is still open, the same hash is kept for 30 days at most, so that the owner can still decide. [This is a provisional choice; the owner and his lawyer decide whether it stays.]
Who else is involved
- Telegram delivers the bot's messages and keeps the photos you send to the bot. Telegram's own terms apply to that.
- Anthropic provides the language model, as described above.
- The parties Roomalert runs on: [hosting of the bot and the website, the database, and the service that sends the mail: name and country to be filled in].
Roomalert does not sell your data and does not pass it on to anyone else.
This website
The website shows yesterday's rooms and two buttons to the bot. It sets no cookies, uses no analytics and loads no fonts, scripts or images from other parties. To deliver the page, the server processes your IP address. [Whether and for how long the server keeps it in log files: to be filled in.]
Erasing everything
Send /verwijder to the bot and confirm. That erases your profile, your mail address, the history of your alerts, your rooms with their text and the references to your photos, and all your conversations with every message in them. Whoever was in a conversation with you gets a short message that it has ended.
Two things remain after that. If you had placed a room, the facts of that room (without text, photos, address or anything that points to you) are kept as a closed room for 90 days at most. And if you were blocked, the hash described under "Blocking" stays.
Your rights
You can ask what Roomalert keeps about you, have it corrected or erased, and object to its use. Mail info@roomalert.nl for that. If you disagree with how Roomalert handles your data, you can file a complaint with the Dutch Data Protection Authority (Autoriteit Persoonsgegevens).
[To be added by the lawyer: the legal basis for each kind of processing.]
