Cookie & Storage Policy
Last updated: July 19, 2026
In short
- velzo sets no marketing or tracking cookies — none.
- We use your browser’s local storage for your preferences and, unless you opt out, anonymous statistics identifiers.
- With Do-Not-Track or Global Privacy Control enabled, no analytics identifiers are created at all.
- Everything below can be deleted in seconds from your browser settings.
“Cookies” is shorthand for anything a website keeps in your browser. Here is velzo’s complete inventory — every key, what it does, and how long it lives.
Your preferences (localStorage)
These make velzo remember your choices between visits. They stay in your browser until you clear them and are never used for tracking.
| Key | Purpose | Lifetime |
|---|---|---|
velzo.lastPair | The language pair you last chose, so the feed resumes where you left off | Until you clear it |
velzo.alwaysReveal | Your “always show the translation” setting | Until you clear it |
velzo.feedTheme | Your dark/light feed preference | Until you clear it |
Anonymous statistics (only if you haven’t opted out)
Random identifiers for the anonymous usage statistics described in the privacy policy. None of these are created when your browser sends Do-Not-Track or Global Privacy Control.
| Key | Where | Purpose | Lifetime |
|---|---|---|---|
velzo.vid | localStorage | Random visitor identifier (a UUID) so repeat visits count as one visitor, not many | Until you clear it |
velzo.sid | sessionStorage | Random identifier for the current session | Deleted when the tab closes |
velzo.sstart, velzo.slast, velzo.sdepth | sessionStorage | Session start time, last activity, and scroll depth — used to measure session length | Deleted when the tab closes |
Cookies from our infrastructure
velzo itself sets no cookies. Cloudflare, which delivers the site and protects it from abuse, may set strictly-necessary security cookies (for example, for bot protection). These are functional, not used for marketing, and outside them there are no third-party cookies of any kind on velzo.
How to clear or opt out
- Delete everything: in your browser’s settings, clear site data for velzo.app. All keys above disappear immediately; velzo keeps working, just with default settings.
- Opt out of statistics permanently: enable Do-Not-Track or Global Privacy Control in your browser or via a browser extension. velzo honors both — analytics are disabled entirely, and no identifiers are created.
Changes
If we ever add a stored key — for example, if advertising is introduced (see the privacy policy) — this table will be updated first, and consent will be requested where required.
