Privacy Policy

This Privacy Policy describes how Tinker Tools ("we," "us," or "our") collects, uses, and protects information when you use our website at tinker.tools (the "Service"). We are committed to safeguarding your privacy and being transparent about our practices.

1. Client-Side Processing

The core principle behind Tinker Tools is local processing. When you use any of our 75+ tools — whether you are formatting JSON, compressing an image, merging PDFs, or running a financial calculator — the work happens entirely in your web browser using JavaScript and WebAssembly. Your input data (text, files, numbers) is never transmitted to our servers or any third-party server for processing. Once you close or refresh the browser tab, all data associated with that session is discarded by the browser.

2. Information We Collect

We do not collect personal information directly. However, the following third-party services operate on our site and may collect certain data:

2.1 Google Analytics

We use Google Analytics 4 to understand how visitors interact with the site — which pages are visited, how long sessions last, and what regions our users come from. Google Analytics uses cookies and collects anonymized usage data. It does not have access to the content you enter into our tools. You can opt out of Google Analytics by installing the Google Analytics Opt-out Browser Add-on.

2.2 Google AdSense

We display advertisements through Google AdSense to support the ongoing development and hosting of Tinker Tools. AdSense may use cookies and web beacons to serve ads based on your prior visits to this and other websites. You can review and control ad personalization at Google Ads Settings. You may also visit aboutads.info to opt out of personalized advertising from participating companies.

3. Cookies

Tinker Tools itself does not set any first-party cookies. The only cookies on the site come from Google Analytics and Google AdSense, as described above. You can manage or block cookies through your browser settings. Blocking cookies will not affect the functionality of any tool on the site.

4. Data Retention

Since tool inputs are processed locally and never reach our servers, there is no server-side data to retain. The Google Analytics data retention period is set to 14 months, after which aggregated data is kept but individual-level data is deleted. We do not maintain any database of user-submitted content.

5. Third-Party Links

Our site may contain links to external websites. We are not responsible for the privacy practices of those sites. We encourage you to read the privacy policies of any third-party site you visit.

6. Children's Privacy

Tinker Tools is not directed at children under the age of 13. We do not knowingly collect personal information from children. If you believe a child has provided us with personal data, please contact us so we can take appropriate action.

7. Security

We serve the site over HTTPS to protect data in transit. Because user-generated content is processed locally, there is minimal attack surface for data breaches related to tool inputs. We regularly update our dependencies and infrastructure to address known vulnerabilities.

8. International Users

Tinker Tools is hosted on a global CDN. Google Analytics and AdSense data may be processed in the United States or other countries where Google operates. By using the Service, you acknowledge that anonymized analytics data may be transferred internationally.

9. Changes to This Policy

We may update this Privacy Policy from time to time. When we make changes, we will revise the "Last updated" date at the top of this page. We encourage you to review this policy periodically.
