Cookie Policy

SnapToolz's own code sets no cookies. The cookies you may see in your browser come from the third-party advertising and analytics services that keep the site free. Every one is listed below, along with how to opt out.

Last updated: May 30, 2026

No first-party cookies

SnapToolz's own code does not set HTTP cookies. There is no server-side session because there is no server that handles your data.

Tiny localStorage

A handful of small string values store your preferences (theme, language, favorites). Listed in full below.

Third-party ad cookies

Google AdSense and (when enabled) Google Analytics set their own cookies. They are documented in the table below with opt-out links.

First-party storage SnapToolz uses

Open DevTools → Application → Local Storage to verify.

  • snaptoolz.locale

    Your selected interface language

    Why we store it: So the site stays in your chosen language across visits

    Example value: "hi" or "en"

  • snaptoolz.user-prefs.v1

    Your favorite tools, pinned tools, recent tool views, and recent searches

    Why we store it: Powers the homepage shelf and the command palette suggestions — entirely client-side, never sent anywhere

    Example value: { "favorites": ["/pdf/merge"], "recentSearches": ["pdf"] }

  • snaptoolz.install-prompt.dismissed-at

    Timestamp of the last time you dismissed the install prompt

    Why we store it: So we don't keep nagging you for 14 days after you say no

    Example value: "1717718400000"

  • theme

    Your light / dark mode preference

    Why we store it: So your theme choice survives page reloads

    Example value: "dark"

Third-party cookies set on SnapToolz

Set by Google's advertising and analytics products. Names and durations come from Google's public documentation and may change.

  • __Secure-3PSID, __Secure-3PSIDCC, __Secure-3PAPISID, __Secure-3PSIDTS

    Typical duration: Up to 2 years

  • IDE

    Set by: Google DoubleClick (doubleclick.net)

    Measures the effectiveness of ads, helps with reporting on which ads have been shown and clicked, and limits how many times you see the same ad.

    Typical duration: Up to 13 months

  • NID

    Set by: Google (google.com)

    Carries Google's preferences for ad customisation and remembers settings such as your preferred language and the number of search results to show.

  • ANID

    Set by: Google (google.com)

    Used by Google AdSense to make advertising more effective across sites that use AdSense.

    Typical duration: Up to 13 months

  • _ga

    Set by: Google Analytics (only when GA is configured)

    Distinguishes unique visitors by assigning a randomly generated client-side identifier. Aggregated only — no individual user tracking.

    Typical duration: 2 years

  • _ga_<container-id>

    Set by: Google Analytics (only when GA is configured)

    Persists the session state for GA4 property reporting.

    Typical duration: 2 years

Opting out of advertising cookies

You can disable personalised advertising and the storage of advertising cookies through any of these channels:

  • Google ad-personalisation controls: google.com/settings/ads
  • EEA / UK / Swiss visitors — use the consent prompt Google's ad units show on first load
  • US industry-wide opt-out: optout.aboutads.info
  • EU industry-wide opt-out: youronlinechoices.eu
  • Browser-level tracking-protection (built-in shields, uBlock Origin, Privacy Badger, etc.) — blocking AdSense will not break any SnapToolz tool

See the privacy policy for the full list of third-party services and your data-protection rights.

Service worker cache

SnapToolz uses a service worker (the standard web platform feature) to cache the app's own JavaScript, CSS, fonts, and icons. This is what makes SnapToolz work offline and load instantly on repeat visits.

The cache contains no user data— only SnapToolz's own files. You can clear it at any time from your browser's Site Settings or by reinstalling the PWA.
