What we keep in local storage
| Key | Purpose and lifetime |
|---|---|
| leviro-theme | Remembers whether you chose light or dark mode. Kept until you clear it. |
| leviro.ref | A referral code from a ?ref link, so credit reaches the right person if you sign up later. Automatically discarded after 30 days. |
| leviro.utm | utm_source / utm_medium / utm_campaign values from the link you arrived on, used to attribute a signup to a campaign. Automatically discarded after 30 days. |
| leviro.analytics-consent | Stores accepted or declined for optional first-party product analytics. Kept until you clear site data or change the choice. |
The referral and campaign values are sent to us only once, attached to a signup request. If you never register, they expire in your browser and we never receive them.
If analytics is accepted, session storage also holds a random analytics session ID plus one-time markers that prevent duplicate view, input, and success events. Session storage is cleared when the browser session ends and contains no email, filename, document text, or tool input.
Offline caches
Leviro Toolbay is installable as a progressive web app. When you install it — or simply visit it — a service worker caches pages, icons, styles, and scripts in your browser so tools keep working offline and load faster. This cache holds application assets, not your content.
The high-quality local text-to-speech voice also downloads its model into your browser's storage the first time you use it, so later runs are instant and stay entirely offline. That model file can be large; clearing site data removes it.
Third-party requests
The Arabic and English interface fonts are hosted by Leviro Toolbay and do not contact a font CDN. Google Sign-In loads Google's script only on the login and registration pages, and only if Google sign-in is enabled. We do not use it to track you across sites, and it does not set a cookie on our domain.
Controlling all of this
- Signing out clears the session cookies and revokes the refresh token on our side.
- Clearing site data in your browser removes the cookies, theme and referral entries, analytics choice and session, offline cache, and any downloaded voice model.
- Blocking cookies for this site entirely is fine — you simply will not be able to stay signed in. Every browser-based tool keeps working.
