Welcome to Tip Calculator ("we", "us", or "our"). This Privacy Policy explains how we handle information when you visit tipcalculatoror.wiki or use the browser-based tip and tax calculators. The basic calculator lets you enter bill values, tax rates, tip percentages and group sizes without creating an account or sending those calculation values to a calculation server.
1. Browser-based calculations
The core tip, tax, total and bill-splitting calculations run locally in your browser. The values you type into the calculator are used by the page to produce the result on your device. The ordinary calculation flow does not require us to upload your bill amount, tax rate, tip percentage or number of people to a server.
Local calculation is a convenience, not a promise that every network request on a website is private. The page may load hosting, analytics, advertising or other third-party resources described below. Do not enter information that you do not want exposed through a browser, network or third-party service.
2. Information we may collect
- Usage data: pages visited, browser type, device category, language, referral source, approximate region and timestamps.
- Technical logs: IP address, request information, error logs and security events needed to operate and protect the site.
- Support communications: messages sent to our support email, including the contact details and problem description you choose to include.
- Preference and interaction signals: language selection, page interactions and basic events used to understand whether the calculator is usable.
We do not require an account for the basic calculator and do not intentionally collect a profile of your private financial life from the bill values used in the local calculation. If a future feature adds accounts, payments or server-side storage, this policy will be updated before that feature handles personal data.
3. How we use information
- Operate, maintain and improve Tip Calculator.
- Understand which pages, calculator controls and explanations are useful to visitors.
- Monitor performance, accessibility, mobile layout and reliability.
- Protect the site from abuse, spam, fraud and security incidents.
- Respond to bug reports, corrections, feedback and support requests.
For example, aggregate usage data can show whether visitors reach the calculator, whether a mobile control is difficult to use or whether a page error affects a result. We use this context to improve the site and its explanations, not to make decisions about a visitor based on a private bill.
4. Cookies, web beacons and analytics
We may use necessary cookies, analytics technologies and similar identifiers to keep the site available, understand performance and measure visitor behavior. Analytics may record page views, device category, browser version, approximate region, referral source, session timing and interaction events. IP addresses and other technical identifiers may be processed as part of these services, subject to the providers' own policies.
You can control or delete cookies through your browser settings. Blocking analytics may not prevent the calculator from working, although some measurement features may become less accurate. Necessary hosting, security or cache behavior may still occur because those systems help deliver the website.
5. Advertising and Google services
If advertising is served on the site, Google and other third-party advertising or measurement providers may place or read cookies on your browser, use web beacons or process IP addresses and other identifiers to serve, measure or limit advertising. These providers may use information about visits to this and other websites as allowed by their terms, applicable law and your consent choices.
For information about how Google uses data when you use partner websites and applications, see Google's partner-site data-use explanation. The presence of an advertising account, ads.txt entry or advertising code does not mean that every visit receives a personalized advertisement.
6. Sharing and disclosure
We do not sell personal information. We may share limited information with hosting, analytics, security, email, advertising or legal service providers when needed to operate the website, measure performance, serve or report advertising, prevent abuse, answer support requests or comply with law. Those providers may process information under their own terms and privacy commitments.
We may disclose information when required by legal process, when needed to protect the site or users, or if the website is transferred as part of a business transaction. We aim to share only information reasonably necessary for the specific purpose.
7. Data retention and security
We retain usage logs and support communications only as long as reasonably needed for site operation, security, analytics, support and legal compliance. Support messages may be kept long enough to resolve a request. Server logs may be retained for security review and later deleted or aggregated. We do not intentionally retain the ordinary bill values entered into the local calculator as a server-side account record.
We use reasonable technical and organizational measures to operate the site and reduce common security risks. No website can promise perfect security, and browser tools still depend on your device, browser and network. Keep your browser updated and contact us if the calculator behaves unexpectedly.
8. Your choices and rights
You can choose not to use the calculator, clear local browser data, adjust browser cookie settings and decline optional analytics or advertising choices where a consent control is provided. Some necessary site functions may not work correctly if essential cookies or scripts are blocked.
Depending on your location, you may have rights to access, correct, delete, restrict or object to certain personal information, and to withdraw consent where processing depends on consent. To make a request, contact [email protected]. We may need enough information to verify the request and locate relevant records.
9. Children and external links
Tip Calculator is a general-audience website. We do not knowingly collect personal information from children under 13. If you believe a child sent personal information through support email or another channel, contact us so we can review and delete it where appropriate.
The site may link to external resources, policies or related tools. External websites have their own privacy practices, and we are not responsible for their policies. Review those policies before sending information to another service.
10. Changes to this policy
We may update this Privacy Policy by changing the content and effective date on this page. Updates may be needed when the site changes hosting providers, analytics tools, advertising services, support workflows or calculator behavior. Continued use of the site after an update means the revised policy applies to future use.
