This Privacy Policy (“Policy”) explains the information collection, use, and sharing practices of Classroom Timer (“we,” “us,” and “our”), a Chrome extension that provides a fullscreen classroom countdown timer and stopwatch.
The short version: we do not collect any information from you, in any form, for any purpose. The sections below follow a standard privacy-policy structure and explain, category by category, exactly what does and does not apply to this extension.
Classroom Timer has designed this policy to be consistent with the following principles:
We do not collect information about you, whether you provide it directly, whether it would otherwise be collected automatically from your browser or device, or from any third party. The subsections below confirm this for each category a policy like this normally covers.
Classroom Timer has no account creation, sign-in, purchase flow, donation flow, newsletter, or feedback form of any kind. There is no field anywhere in the extension where you are asked to type your name, email address, phone number, payment information, or any other personal detail.
The extension does not automatically collect device or usage information of any kind: no IP address, no location, no device identifiers, no browser or operating system details, no click or navigation data, and no error logs are gathered or transmitted anywhere.
The extension uses no cookies, tracking pixels, web beacons, or similar tracking technologies, either in the extension itself or on this page.
We do not receive information about you from any third party, public source, social media platform, or research firm.
Because no information about you is collected, none is used. The one exception is entirely local: the extension saves your last-used timer duration, alarm sound, and light/dark theme preference, and the state of an active countdown, using your browser's local storage on your own device. This local data is never transmitted to us or to anyone else, is never analyzed, and is used only to restore your preferences the next time you open the timer.
We have nothing to disclose, because we collect nothing. For completeness, here is how this section applies to each circumstance a policy like this normally covers:
Not applicable. We use no service providers to store, analyze, or process user data, because no such data exists.
If we were ever compelled by legal process to disclose information, we would have nothing relevant to disclose, since we do not collect or retain personal information in the first place.
If Classroom Timer is ever transferred to a new owner or operator, there is no user database or personal information to transfer along with it, because none exists.
Not applicable. There is no user information to share with any affiliated company.
Not applicable. We never ask you for information, so the question of consenting to share it does not arise.
Not applicable. We do not produce aggregate or de-identified data sets, because there is no underlying data to aggregate or de-identify.
Some jurisdictions require us to state the legal ground for processing personal data. Because we do not process personal data, none of the grounds below actually apply to us — they are listed here only for completeness.
Not applicable. The extension involves no account, subscription, or contract that would require processing your data.
Not applicable.
We comply with applicable law. In our case this is simple to do, since there is no personal data on file that any legal process could ever reach.
Not applicable, for the same reason given above.
We do not use Google Analytics or any other third-party analytics, advertising, or tracking service — not in the extension, and not on this page.
You have no data to manage with us, because we hold none. For completeness:
Not applicable. We send no marketing email and maintain no mailing list.
Not applicable. There is no account and no account settings to adjust with us.
Individuals in the European Economic Area and other jurisdictions have rights to access, correct, or delete personal data held about them. Because Classroom Timer holds no personal data about you, there is nothing to access, correct, or delete. If you still have a question, email us at alekseyz@wedo4u.app and we will respond.
Not applicable. No information about you is transferred anywhere — domestically or across borders — because none is collected in the first place.
There is no server on which user data is stored, so there is no server-side data to secure. The only information related to your use of the extension lives in your browser's local storage on your own device, protected by the normal security of your operating system and browser profile.
Classroom Timer is built for classroom use and is expected to be used by students, including children. Because this Policy applies equally to every user regardless of age, and because we collect no personal information from anyone — adult or child — there is no personal information belonging to a child for us to collect, store, or disclose. This is true whether the extension is opened by a teacher, displayed on a shared classroom screen, or used directly by a student.
We retain nothing, because we collect nothing. Information stored locally in your browser (your last-used settings, described above) remains on your device until you clear your browser data or remove the extension, at which point it is deleted along with everything else the extension stored.
The extension contains no links to third-party websites, no embedded third-party widgets or plug-ins, and no embedded third-party services of any kind.
We will continue to evaluate this Policy as the extension evolves. If we ever make a change, we will post the updated Policy on this page and revise the “Last Updated” date above. We encourage you to check this page periodically. If we make a material change — for example, if the extension ever began collecting any information it does not collect today — we will provide notice as required by law.
