WatchOut.run

Privacy

Last updated 8 August 2026

WatchOut.run has no accounts, no login, no cookies and no analytics. It stores nothing about you. Everything below follows from that, with one narrow, self-destructing exception described under “The routes mailbox”.

What we collect

Nothing. Workouts, calendar events and workout pages are generated on the fly from the parameters in the URL (or the arguments of an MCP tool call) and returned in the response. We keep no database and no user profiles. The MCP server at mcp.watchout.run is stateless — it holds no memory of you between calls. Standard, ephemeral request logs may be processed by our host, Cloudflare, to run and protect the service; we do not build profiles from them.

The routes mailbox

When your assistant asks for your saved Strava routes, the routes page can send them back automatically instead of you copy-pasting. That hop works through a one-shot mailbox on our server: your browser encrypts what you selected (AES-GCM) with a key that travels only in the link's fragment — the part after #, which browsers never send to any server — and parks the ciphertext for at most 15 minutes. Your assistant collects it once, which deletes it; uncollected entries expire on their own. We cannot read what's in the mailbox (we never see the key), there is no index of mailboxes, and nothing about it identifies you. Prefer not to use it? The copy-paste block on the same page does the same job with no server in the middle.

Your data stays with you

If WatchOut.run goes away

Storing nothing is a promise about your data, and also a dependency you should be able to see: because the workout lives in the link, some of what you have here needs this site to keep answering. The honest breakdown, so nothing about it is a surprise:

So a calendar event keeps telling you what the session is even if this site stops answering; the link on it is what would stop working. The code is written to be deployable by anyone for that reason — the service is a single stateless worker with no database to migrate and no secrets to hand over.

Third parties

Some features send data you provide to services you choose to use, under their own privacy terms:

Children

WatchOut.run is a general-audience fitness utility and is not directed to children under 13.
