Cookies and Local Storage

• Sign-in session

  Local storage · Strictly necessary

  Keeps you signed in between visits and lets the app talk to the backend as you. Removed when you sign out.

• Encryption key material

  Local storage · Strictly necessary

  Holds your wrapped encryption key on this device so protected case content can be decrypted locally. It never leaves the browser.

• tw_analytics_consent / tw:analytics_consent

  Cookie and local storage · Preference

  Records whether you allowed product analytics, so we do not ask again on every visit. Mirrored across stores only so the banner cannot reappear after you answer.

• tw.changelog.lastSeen

  Local storage · Preference

  Remembers the newest release you have already read, so 'What's new' is accurate.

• Onboarding and interaction markers

  Local storage · Preference

  Device-local hints such as which setup screen you were last on, or a dismissed prompt. They never contain case content and are cleared when the flow completes.

• Product analytics events

  Local storage · Analytics (opt-in)

  Coarse, anonymous counters used to understand which pages help. Written only after you opt in, never containing names, case content, or free text.

Product analytics are off until you turn them on. We ask once, store your answer, and honour it. You can change your mind at any time from the consent control in the site footer, and declining changes nothing about how the product works.

If your browser sends a Do Not Track or Global Privacy Control signal, analytics stay off regardless of any stored choice, and we do not ask.
