Privacy Policy

Last updated: November 3, 2026

This policy explains what information Devsens ("we", "us"), the operator of the SRT Merger website and tool, handles when you use this site. We have tried to write it in plain language.

The short version

  • Subtitle files you open in the tool are processed inside your browser. They are not uploaded to our servers or to anyone else.
  • We do not ask you to create an account.
  • Like any website, our hosting provider records basic technical logs when pages are requested.
  • If you contact us, we receive the details you send.
  • Analytics and advertising cookies are off until you accept them in the cookie banner. You can change your choice at any time with the "Cookie settings" link in the footer.
  • If advertising is shown on the site, advertising partners may use cookies, as explained below.

Files you process with the tool

When you choose or drop an .srt file, your browser reads it from your device and our page code compares it in your computer's memory. The file's content is never sent over the internet by the tool. When you save, the merged file is written back to your device. We cannot see, access or recover your files, and we do not keep copies. You can verify this by watching the Network tab of your browser's developer tools or by using the tool offline once the page has loaded.

Information stored in your browser

To open the file picker in the folder you used last, supported browsers (such as Chrome and Edge) store a reference to your most recently chosen file in your browser's local storage (IndexedDB) on your device. It stays on your device, is not sent to us, and can be removed by clearing site data in your browser settings. We also store your cookie choice in your browser's local storage (key srt_consent) so that we do not ask you again on every visit. The site does not otherwise use cookies for its own functions.

Information collected automatically

The site is hosted on Firebase Hosting, a service of Google. When you request a page, the hosting infrastructure processes technical information such as your IP address, browser type, requested page, date and time, and referring page. This is used to deliver the site, keep it secure and diagnose faults. We do not use this to identify you. Google processes this information under its own terms and privacy policy.

Analytics

We may use Google Analytics (a service of Google) to understand how the site is used, for example which pages are visited and how visitors find us, so that we can improve the tool and guides. Google Analytics loads only after you click Accept in the cookie banner. If you choose Reject, or make no choice, it is not loaded and no analytics cookies are set.

When enabled and accepted, Google Analytics sets cookies such as _ga and _ga_<ID> (typically lasting up to two years) and collects information such as pages viewed, approximate location derived from your IP address, device and browser type, and referring site. This information is processed by Google under its own terms. Google Analytics never receives the contents of your subtitle files, which stay in your browser. You can withdraw consent at any time using "Cookie settings" in the footer, and you can also use the Google Analytics opt-out browser add-on.

Contact form and email

Devsens is the controller of the personal data described in this section. If you write to us, we receive your name, email address and message, and any other details you include. We use them only to respond to you, to improve the site, and to keep a record of correspondence. Messages sent through the form are stored in a Google Firebase (Cloud Firestore) database that only the site operator can read. Please do not include private subtitle content or sensitive personal information in your message. We keep correspondence only as long as needed to handle your request and for reasonable record keeping, and you can ask us to delete it.

Advertising and third-party cookies

We may display advertising on this site, including ads served by Google AdSense. If ads are shown, third-party vendors, including Google, use cookies or similar technologies to serve ads based on your previous visits to this and other websites. Google's use of advertising cookies enables it and its partners to serve ads based on your visit to this site and other sites on the internet.

  • You can opt out of personalised advertising by visiting Google Ads Settings.
  • You can also opt out of some third-party vendors' use of cookies for personalised advertising at aboutads.info.
  • Where required, such as in the European Economic Area, the United Kingdom and Switzerland, we ask for your consent before personalised ads or non-essential cookies are used, and you can change your choice at any time.

Advertising partners do not receive your subtitle files, because those never leave your browser. Third parties that serve ads have their own privacy policies, which we do not control.

Legal bases (EEA, UK and similar regions)

Where data protection law such as the GDPR applies, we rely on: our legitimate interest in running and securing the website; your consent for non-essential cookies and personalised advertising; and, for correspondence, our legitimate interest in answering you or steps you ask us to take.

Your rights

Depending on where you live, you may have the right to access, correct, delete or restrict the use of personal data we hold about you, to object to certain processing, to withdraw consent at any time, and to complain to your local data protection authority. Residents of California and some other US states have comparable rights, including the right to know and delete, and the right to opt out of the sale or sharing of personal information. We do not sell personal information. To exercise a right, send us a request or write to connect.devsens@gmail.com.

Children

This site is not directed at children under 13, and we do not knowingly collect personal information from them. If you believe a child has sent us personal information, contact us and we will delete it.

Security

The site is served over HTTPS. Because your subtitle files never leave your device, the main security measure for them is not to send them anywhere. No method of transmission or storage is completely secure, so we cannot guarantee absolute security for messages you send us.

International transfers

Our hosting and service providers may process data in countries other than your own. Where required, they rely on legal safeguards for such transfers.

Links to other sites

Our pages link to other websites, such as the open-source project page. We are not responsible for their content or privacy practices.

Changes to this policy

We may update this policy as the site changes. The date at the top shows when it was last revised. Significant changes will be highlighted on this page.
