Last updated: November 8, 2026
This Privacy Policy applies only to Port to Port – Distance & ETA Calculator (the “app”), available for Windows, iPhone and Android, and to its download and feedback pages on ilginozgul.academy. It does not cover other apps or the rest of this website.
The short version
- Port to Port works offline. It has no accounts, no ads and no analytics or tracking tools.
- The app does not collect, store or share your personal data.
- If you choose to send feedback, we receive only what you type and the details shown on the feedback page.
Who we are
Port to Port is developed by a seafarer, for seafarers, and published through ilginozgul.academy. You can contact us at any time through the feedback page.
What the app does with your data
All calculations (distances, passages, speed, time and arrival time) happen on your device. The choices you make in the app stay on your device. The app does not ask for your name, email address, location or any other personal information, and it does not use advertising or analytics services.
Update checks (Windows)
The Windows app may check for new versions by requesting a small file from ilginozgul.academy. Like any web request, this lets our web server see technical information such as your IP address, the time of the request and your app version. Our hosting provider keeps standard server logs for security and operation. We do not use this information to identify you and we do not combine it with anything else.
Sending feedback
The app may open our feedback page in your browser. If you send a message, the following information is emailed to us:
- the type of problem you selected and the message you wrote;
- your email address, only if you choose to enter it (so we can reply);
- when you report a route: the departure and arrival ports, the distance shown, the closed passages, and the app version and platform (for example “Port to Port 1.1 · iOS”). These details are displayed on the page before you send.
We use this only to understand and fix problems, to improve the app and, if you gave an email address, to reply to you. Messages are not saved in the website’s database; they exist only in our email inbox. To prevent spam, the feedback page uses a hidden trap field and a short-lived rate limit that keeps a shortened, non-readable fingerprint of your connection for up to one hour. The feedback page does not use cookies, analytics, advertising or external fonts.
Sharing
We do not sell, rent or share your information. Feedback emails are handled by our own email and hosting services, which process them only to deliver them to us.
Retention and your choices
We keep feedback emails only as long as they are useful for fixing or improving the app. If you would like a message you sent to be deleted, tell us through the feedback page and we will delete it. Because the app itself collects no personal data, there is nothing stored about you in the app to access or delete.
Children
Port to Port is a tool for seafarers and is not directed at children. We do not knowingly collect personal information from children.
Changes to this policy
If the app changes in a way that affects your privacy, we will update this page and the date above.
