Radar privacy notice
Last updated: 9 October 2026
This notice covers CNTRL Radar, an internal tool that Cntrl Software GmbH uses to follow public conversations about website builders on Threads. It does not cover Control, our website builder. For that, see our privacy policy.
Who we are
Cntrl Software GmbH, Seidlgasse 12a, 1030 Vienna, Austria (FN 621497t) is responsible for the data described here. Contact: arsen@cntrl.site.
What the radar does
Once a day the radar reads public Threads posts through Meta's Threads API:
posts that contain phrases people use when choosing a website builder, such as "portfolio website" or "squarespace alternative"
posts that mention our account @control_tool
replies under posts by @control_tool
Our team reads the relevant ones and, where we can genuinely help, replies by hand from @control_tool. The radar never posts, replies, likes, follows or sends messages.
What we store
For each post: its ID, text, link, time, the author's public username, and whether it is a reply. We collect nothing beyond what the post itself makes public. We don't build profiles of authors, and we don't combine posts with other data about them.
Why, and on what legal basis
To find and answer people who are looking for a website builder, and to respond to people who talk to us. The legal basis is our legitimate interest in managing our presence on Threads (Art. 6(1)(f) GDPR). The data is public, we only read it, and anyone can ask us to delete it.
Who else handles the data
TypeSafe reads post text to classify whether a post is asking for help with a website.
Slack carries the alerts to our team's private channel.
Both act on our behalf only and may process data outside the EU under standard contractual clauses. We do not sell the data, use it for advertising, or use it to train models.
How long we keep it
30 days. After that the posts are deleted, and we keep only counts, such as how many posts matched a phrase.
Your rights
You can ask us for a copy of what we hold about you, to correct it, to delete it, or to stop processing your posts. You can also complain to the Austrian Data Protection Authority (Datenschutzbehörde, dsb.gv.at).
