Privacy Policy

AllCalculator does not require you to provide your name, email address, phone number, mailing address, password, or other profile information to use the calculators.

We do not intentionally build user profiles from calculator activity, and we do not operate a user-account database for normal calculator access.

As with nearly every website, basic technical request information may still be processed automatically by the systems that deliver and protect the site. This can include an IP address, browser or device information, requested URL, date and time of the request, and similar network-level information. Such processing can occur at the hosting, content-delivery, or security layer even when AllCalculator itself does not create a user profile.

Values you enter into AllCalculator tools are used to perform the requested calculation. Our calculators are designed so that these values are not intentionally saved to an AllCalculator database.

For example, if you enter a loan amount, body measurement, construction dimension, percentage, date, or other calculator value, that information is intended to be processed for the calculation and not retained as a personal record by AllCalculator.

We do not intentionally use calculator inputs to create advertising profiles, identify individual users, or sell information to data brokers.

Because browser behavior, extensions, device settings, network software, or hosting infrastructure are outside our direct control, users should still avoid entering highly sensitive personal information into any website when it is not necessary for the calculation.

AllCalculator tools are designed to be login-free. You do not need to register, create a username, choose a password, or maintain a profile to use the calculators.

Because normal calculator use does not require an account, we do not need to collect account credentials or maintain account histories for calculator access.

AllCalculator's privacy-first configuration does not require advertising cookies, behavioral tracking cookies, or third-party analytics in order for the calculators to work.

We do not use calculator inputs for cross-site behavioral advertising.

Essential infrastructure or security systems may use temporary technical mechanisms where necessary to deliver the site, prevent abuse, or protect availability. These are operational rather than calculator-profile features.

AllCalculator does not sell, rent, or intentionally share calculator input values with advertisers, marketers, or data brokers.

Calculator results are not intentionally sent to third parties for profiling or advertising.

The site may rely on infrastructure providers to host, deliver, secure, or cache website files. Those providers can process ordinary network request information as technically necessary to provide those services. This is different from AllCalculator intentionally sharing your calculator inputs or building a personal data profile.

AllCalculator does not intentionally store calculator inputs in a user database. Because the site does not require user accounts for calculator access, there is also no calculator account history that users need to maintain.

We use reasonable technical measures appropriate for a public website, including HTTPS, to help protect data transmitted between your browser and the site.

No internet service can guarantee absolute security. Network providers, browsers, device software, and security systems may process technical information as part of normal internet operation.

AllCalculator does not sell personal information.

We do not sell calculator inputs, calculator results, or personal profiles to advertisers or data brokers.

If the site's advertising or tracking practices ever materially change, this Privacy Policy should be updated to explain the change before the new practice is introduced.

AllCalculator does not require personal accounts and does not intentionally collect personal profile information from children through calculator use.

Some calculators may address subjects intended for adults or require adult interpretation. Parents, guardians, teachers, and users should use appropriate judgment when choosing calculators or interpreting results.

AllCalculator pages may occasionally link to external resources for references, documentation, standards, or additional information.

Once you leave AllCalculator, the privacy practices of the external website apply. We do not control how another website collects, stores, or uses information.

Because AllCalculator does not intentionally maintain calculator-input records, there may be little or no calculator-specific user data available to disclose.

If legally required, we may comply with valid legal obligations relating to information that is actually available to us or to the infrastructure used to operate the website.

We may update this Privacy Policy if the website's features, technology, legal requirements, or data practices change.

When the policy changes materially, the updated version should be posted on this page with a revised “Last updated” date.

If you have a question about this Privacy Policy, use the contact channel published on AllCalculator.io, when available.
