Tokkucal
Privacy Policy
Last updated: 29 September 2026
Tokkucal ("we", "us") provides free online calculators and utility tools at this website. This policy explains what data is involved when you use the site and why.
No account, no stored calculations
Tokkucal does not require you to create an account or log in. The numbers you enter into a calculator, and the results shown, are not saved to a database or linked to you in any way.
Image and QR code tools
Images uploaded to the Image Compressor or Image Resizer are processed in memory on our server and returned to your browser in the same request. They are never written to disk or kept after the response is sent. The QR Code Generator runs entirely in your browser — the content you turn into a QR code is never sent to our servers at all.
Contact form
If you use the contact form, the name, email address, subject and message you provide are sent to us by email so we can respond. This information is not stored in a database or used for marketing.
Essential Cookies
Tokkucal uses a session cookie to keep the site secure (for example, to prevent cross-site request forgery). This cookie does not identify you personally and expires automatically.
Analytics
We may use Google Analytics to understand overall traffic and which tools are popular. If enabled, it uses cookies to collect anonymised usage information such as pages visited, approximate location and device type. This data is not linked to your name or contact details.
Advertising and Cookies
We have applied to use Google AdSense on Tokkucal. Once approved or activated, Google and other third-party advertising vendors may use cookies or similar technologies to serve ads and measure how they perform. These cookies can be used to personalise ads based on your visits to this and other websites, unless you have opted out or your region requires a consent choice first. For visitors in the European Economic Area, the United Kingdom and Switzerland, a consent message is shown before any personalised advertising cookies are set, managed through Google's certified consent management platform. You can review or change your ad personalisation settings at any time in Google Ads Settings, and learn more about how Google uses data from partner sites in Google's Privacy & Terms.
Server logs
Like most websites, our server automatically records basic technical information for security and troubleshooting purposes — such as IP address, browser type and pages requested. These logs are used only to keep the service reliable and secure, and are not used to build a profile of individual visitors.
Data Retention
We keep information only for as long as necessary for the purpose it was collected. Calculator inputs and uploaded images are never stored, as described above. Contact form messages are retained only as long as needed to respond to your enquiry. Standard technical server logs are kept for a limited period for security and troubleshooting purposes.
Your Privacy Rights
Depending on where you live, you may have rights to access, correct or request deletion of personal data we hold about you, and to object to certain processing. Since Tokkucal does not require an account and does not store calculator data, there is typically very little personal data associated with your use of the site beyond what you submit through the contact form. To exercise any of these rights or ask a question about your data, use our Contact page.
Security
We take reasonable technical measures to protect the site and any information submitted through it, including an encrypted (HTTPS) connection and standard security practices. However, no method of transmission over the internet is completely secure, and we cannot guarantee absolute security.
Children's privacy
Tokkucal is a general-audience utility website and does not knowingly collect personal information from children.
Changes to this policy
We may update this policy from time to time. Changes will be posted on this page with an updated date.
