Cookie Policy
Last updated: 24 August 2026 · Version 2.0
This policy describes cookies and similar storage actually used by Senshin. It is not labelled as solicitor-approved. PECR and UK GDPR apply. Necessary cookies do not need consent; analytics and marketing do.

1. Who we are

Alex Sakpoba, trading as Senshin (senshin.io). privacy@senshin.io

2. What cookies are

Cookies are small files on your device. We also use localStorage for the same kinds of job (remembering consent, display settings). This policy covers both.

3. Types we use

Necessary

Required to sign in, keep you in the right workspace, and remember the cookie choice itself. These cannot be switched off in the product; you can block them in the browser, and the app will not work.

Analytics

First-party usage telemetry so we can see which screens fail. Off until you consent. No advertising networks.

Marketing

Only if you consent — campaign tags for in-app onboarding. We do not run third-party ad pixels.

4. Cookie list

NameCategoryPurposeDuration
ss_token Necessary Signed session. httpOnly — not readable by page JavaScript. On *.senshin.io this cookie is scoped to the whole family of subdomains so sign-in at one host works on the others. Session / up to 12 hours, then you sign in again
ss_user_id Necessary Which user the session belongs to, so the workspace can load. Same as session
ss_current_org_id Necessary Which organisation you are currently viewing. A forged value is not trusted on its own — the server checks membership. Same as session
ss_consent_v1 Necessary Your cookie choice, so we can enforce it on the server. 1 year
senshin_consent_v1 Necessary Same choice in localStorage, so the banner does not keep returning. Until you clear site data
ss_settings Necessary Display preferences (theme, density, locale) in localStorage. Until you clear site data
dojo_tester Necessary Set only on the dojo test environment when you enter through a tester invite, so that environment stays isolated. Session
ss_telemetry Analytics Anonymous page and timing events. Only if you allow analytics. Session
ss_campaign Marketing In-app campaign / onboarding tag. Only if you allow marketing. 30 days

5. Third parties that may set their own cookies

We do not load advertising cookies. Third-party sign-in buttons are for signing in, not marketing tags.

6. Changing your mind

Use Cookie Settings in the footer where it is shown, or Settings → Legal. You can also delete cookies in the browser. Blocking necessary cookies will sign you out.

7. Changes

If we add a new optional cookie, we will ask again. The date at the top is the current version.
