Calculator inputs
The core aquarium and pet-cost calculators run in your browser. Tiny Useful Tools does not create user accounts or send the values you enter in those calculators to its application server.
Hosting and basic traffic data
The site is delivered through Cloudflare. Like other web hosts and security providers, Cloudflare may process basic request information needed to deliver and protect the site. The current hosting configuration may also provide aggregated Web Analytics. Tiny Useful Tools does not add names, email addresses, calculator inputs, photos, or custom user identifiers to that analytics data.
Optional Google Analytics
If you choose “Allow analytics,” Tiny Useful Tools loads Google Analytics to measure page views and aggregate events such as opening a tool, starting a calculation, showing a result, copying or sharing, downloading or printing, and following a related-tool link. Our events include the tool name and event type, but not calculator inputs, names, email addresses, photos, or custom user identifiers. Google may process browser and device details, approximate location, and first-party analytics identifiers under its terms. Google Analytics is not loaded when you choose “Essential only.” Your choice is stored in your browser and can be changed below.
Cookies, advertising, and affiliate links
The core calculators do not require advertising cookies, affiliate tracking, or an account. Optional Google Analytics may use analytics storage only after permission; advertising storage and ad-personalization signals remain disabled. If advertising or affiliate links are introduced, this policy and any required consent controls will be updated before that change goes live.
