Incidents

When a promise is broken we say what happened, why, and how it was fixed.

  • Your email was sent to PostHog

    Fixed

    Opened 25 Oct 2026, 18:40 UTC. Fixed 26 Oct 2026, 19:13 UTC. Data: email. Company: PostHog.

    What caused it
    A new growth commit sends the user's email, name and phone to PostHog from the browser, and the user's name and email to Anthropic from the server.
    How it was fixed
    Jotter no longer tells PostHog who the user is, and the AI prompt now holds only the note text.

  • Your email was sent to Meta (Facebook)

    Fixed

    Opened 25 Oct 2026, 14:25 UTC. Fixed 25 Oct 2026, 14:33 UTC. Data: email. Company: Meta (Facebook).

    What caused it
    A marketing tag in the JOTTER_TAGS setting sent the hashed email from the browser to www.facebook.com.
    How it was fixed
    Every Jotter page now has a Content Security Policy that lets the browser talk only to Jotter and PostHog, so the Meta tag can no longer send data.

How we check

A robot signs up to Jotter as a pretend person, with an email, name, phone number and private note that exist nowhere else.

While it uses the app, we capture everything that leaves the browser and everything our servers send out, and look for those fake details, even scrambled ones.

Real users' data is never used for these checks.
