Cookie Policy
This page lists every cookie and piece of browser storage Payzio.ai uses, what it is for, and how long it lasts. We group them into two categories: essential (required for the product to work — used without consent, on the legal basis of providing the service you asked for) and analytics (used only if you opt in).
Essential cookies and storage
These are required to sign you in, keep the app secure, and make it fast. They do not track you across other sites.
| Name | Type | Purpose | Duration |
|---|---|---|---|
| payzio_refresh_token | Cookie (HttpOnly, set by our API) | Your sign-in: lets the app renew your access without asking for your password again. Scripts cannot read it. | Until you close the browser; if you choose to stay signed in, 30 days after your last visit (90 days at most) |
| payzio-auth-session | Cookie | Tells the site you are signed in, so it opens the app instead of the sign-in page. Holds no credentials. | Same as your sign-in |
| NEXT_LOCALE | Cookie | Remembers the language you chose for the site. | 1 year |
| payzio-plan:v1 | Cookie | Remembers your plan so the app menu renders correctly before your account loads. | 1 year |
| payzio-scenarios:v1 | Cookie | Remembers your dashboard state so pages render correctly on your next visit. | 1 year |
| payzio-auth-session:v1 / payzio-auth-session:temporary:v1 | Browser storage | Holds a short-lived access token (minutes) while the app is open; your sign-in itself lives in the cookie above. | Until sign-out (or tab close when you did not choose to stay signed in) |
| payzio-account-state:v1, payzio-invoice-state:v5, payzio.invoice-templates.v1, payzio-contract-state:v2, payzio-dashboard-session:v1 | Browser storage | Caches your own workspace data (profile, invoices, templates, contracts) on your device so the app loads instantly. | Until sign-out or cache reset |
| payzio-consent:v1 | Browser storage | Records your cookie-consent choice, with date and version. | Until you change or clear it |
Analytics cookies (opt-in)
We use PostHog for product analytics. Nothing is initialized, no cookie is set, and no event is sent unless you choose Accept analytics in the consent banner or in your settings. If you later withdraw consent, tracking stops and the cookies below are deleted.
| Name | Type | Purpose | Duration |
|---|---|---|---|
| ph_* (PostHog) | Cookie + browser storage | Product analytics (PostHog): page views and product events that help us understand how Payzio is used. Set only after you accept analytics. | Up to 1 year, removed when you withdraw consent |
Changing your choice
You can change your analytics choice at any time with Cookie settings at the bottom of every page, or in Settings → Security → Privacy & consent when signed in. Withdrawing consent stops analytics immediately and removes PostHog cookies from your browser. When this policy changes, we ask again.
For details on what personal data we process and your rights, see our Privacy Policy, which also names who to contact about your data.
