What are cookies?
Cookies are small text files stored on your device when you visit a website. They help the site remember your preferences and improve your experience.
This policy explains which cookies Onesync, a service from Nordic Technologies AB (company reg. no. 559563-9146), uses and why.
The kinds of cookies we use
Necessary cookies (always on)
Required for the site to work. These cannot be switched off.
| Name | Purpose | Lifetime |
|---|---|---|
| sb-*-auth-token | Supabase authentication and session | 1 year |
| onesync_cookie_consent (localStorage) | Stores your cookie preferences in the browser | Until you clear browser data |
| onesync_visitor_id (localStorage) | A pseudonymised online identifier linking the browser or device to your consent preferences and the associated consent log | Until you clear browser data |
| cookie_consent_log (database) | GDPR Art. 7 proof of consent (visitor_id, preferences, hashed IP, user agent, timestamp) | Kept for as long as the consent applies |
| theme | Remembers dark or light mode | 1 year |
About the identifiers: onesync_cookie_consent and onesync_visitor_id are stored locally in your browser by Onesync and are not shared with any external service. onesync_visitor_id is treated as a pseudonymised online identifier and may constitute personal data where it can be linked to a browser, device, IP address or consent log.
Analytics and statistics (requires consent)
Helps us understand how visitors use onesync.se. The measurement is our own, it runs on this domain, and it stores nothing in your browser — no analytics cookies, no fingerprinting and no third-party analytics provider.
| Data | Purpose | Lifetime |
|---|---|---|
| Page address and referring domain | Which pages are visited and where the visitor came from | Kept until further notice |
| utm_* | Which campaign or link the visit came from | Kept until further notice |
| Clicked link (address and text) | Which routes onward are used | Kept until further notice |
| Country and user-agent string | Rough geography and device type | Kept until further notice |
| Hashed IP address | Counting a visitor once per day, without being able to identify you | The salt changes every day |
About the IP hash: the address is never stored in the clear. It is hashed with SHA-256 together with a salt that changes every day, so the same visitor cannot be recognised the following day. No lasting identifier is stored.
