Privacy Policy
What Roomtherm collects, and what stays in your browser.
Last updated:
This policy explains what Roomtherm (roomtherm.com) collects, why, and what you can do about it.
Who is responsible
Roomtherm is run by Alexander Polekha, an individual entrepreneur in Armenia, who is responsible for the personal data described here (the data controller). Contact: the contact form.
Calculator inputs
The calculators work in your browser. The room sizes and options you enter are processed on your device and are not sent to us.
So that a link can reproduce a result, the page writes those numbers into the address bar as query parameters (for example ?l=12&w=14). They are numbers about a room, not about you. When you open or share such a link, the address, numbers included, reaches our host Cloudflare as part of the page request (see Hosting below); the site itself does not log or store it. Page addresses sent to Google Analytics have the query removed.
So that reloading a calculator page returns you to the same place, the page keeps its scroll position (a single number) in this tab's session storage; it is deleted when you close the tab.
Hosting
The site is served by Cloudflare, Inc., which processes technical request data (such as IP address and browser type) to deliver pages and protect the site from abuse, and keeps it as described in Cloudflare's privacy policy. Cloudflare and Google may process data outside your country, including in the United States.
Analytics
With your consent, we use Google Analytics 4 to count visits and a few actions (for example, that a calculation was run, which preset or unit system was picked). Google Analytics sets first-party cookies (_ga and _ga_ followed by an ID) to tell visits apart. We do not send the values you enter, and page addresses are sent without their query string. Google Analytics keeps this data for 2 months, the shortest setting it offers.
Where consent is required (the EEA, the UK and Switzerland), Google Analytics loads only after you agree in the consent banner; without that agreement it is not loaded. Elsewhere it loads by default once the consent service confirms that no consent is needed (our legitimate interest in counting visits to improve the site); if that service does not answer, Google Analytics is not loaded. If you withdraw consent, it stops sending data from the page at once; cookies it already set stay until they expire or you delete them in your browser. See Google's privacy policy.
Advertising
We show ads from Google. Google and its partners may use cookies to show ads based on your visits to this and other sites. In the EEA, the UK and Switzerland this happens only with your consent; you can change your choice at any time through the privacy settings link in the footer. You can also opt out of personalized advertising at Google Ads Settings. See how Google uses data in advertising.
Feedback you send
- What: your vote ("Was this helpful?"), the message you type, and the page it was sent from. We do not ask for your email or name, and we do not reply to messages. Links to other sites are removed from messages when received.
- Spam protection: Cloudflare Turnstile checks that the form is not sent by a bot. To limit how often one connection can send feedback, we store a one-way hash of your IP address with a salt that changes every day; an hourly job deletes hashes older than 24 hours, so none is kept longer than 25 hours. We never store the IP address itself.
- Why: to fix errors and improve the site (legitimate interest). Nothing you send is published.
- Processor: Cloudflare, Inc. (database and Turnstile).
- How long: messages are kept for 12 months; the same hourly job deletes older ones.
- Deletion: a message is not linked to you, so we cannot find it on request; it is deleted after 12 months.
Your rights
Depending on where you live, you may have the right to access, correct or delete personal data about you, and to object to its processing. Use the contact form. You can also complain to your local data protection authority.
Children
Roomtherm is not directed at children under 13 and does not knowingly collect their data.
