Cookie Policy

_Last updated: 2026-05-21_

tool127 is a local-first developer toolbox. Tool inputs and outputs stay in your browser. This policy explains the limited storage used for cookie consent and the optional Google Analytics cookies that load only if you accept analytics.

Necessary storage

We use localStorage keys tool127.cookie-consent.v2 and tool127.consent.analytics to remember your cookie consent choice.

Purpose: remember whether you accepted or rejected optional analytics.
Type: browser localStorage, not a cookie.
Required: yes, because it prevents repeatedly asking for the same choice.
Contents: analytics preference, decision timestamp, and consent version.

Other local storage may be used for app settings, history, snapshots, and tool preferences. That storage supports local functionality and does not send tool content to us.

Optional analytics cookies

Analytics is optional and off by default. If you accept analytics, tool127 loads Google Analytics 4 to collect aggregated usage statistics, including page views, device/browser information, approximate location, and interactions.

Google Analytics is configured with Consent Mode v2:

analytics_storage is denied by default.
analytics_storage becomes granted only after you accept analytics.
ad_storage, ad_user_data, and ad_personalization stay denied because this site does not use ads.

Example Google Analytics cookies may include:

_ga
_ga_<container-id>

Retention

The consent localStorage values remain until you change your choice, clear site data, or the consent version changes.

Google Analytics cookies may persist according to the Google Analytics settings configured for this site and Google's own retention behavior.

User control

You can reject analytics on first visit. Rejecting analytics does not block access to the website.

You can change your cookie settings later from the footer. If you turn analytics off, Consent Mode is updated to denied and future analytics page views and events are blocked.

You can also clear stored choices and analytics cookies by clearing site data for tool127.com in your browser.
