CinemaWide - Privacy policy
Last updated: 11 November 2026
CinemaWide is a free Chrome and Firefox extension developed by Jabed Ahmed, who is responsible for the personal information described in this policy. Contact: jabed098@gmail.com.
1. Everyday use stays on your device
CinemaWide adjusts existing website video players, page width, supported links and browser-tab audio. During normal use, it does not send your browsing activity, video, settings or other page contents to the developer. It has no analytics, advertising, tracking SDK, user account or browser cloud sync, and does not sell personal information. The optional feedback form is described below.
2. Page and tab access
The extension accesses page video elements and recognised link destinations, uses website hostnames to choose preferences, opens tabs when you click supported links, and reads tab audio/mute state to manage background sound. Background-video pausing is enabled by default and configurable per website. When enabled, it pauses eligible playing videos and keeps temporary ownership information with each video so it resumes only videos it paused. Manually paused videos are not automatically resumed. Navigation-source information lets a new same-site tab keep its source tab's group, while different websites open outside that group. These operations take place locally; CinemaWide does not build a browsing-history log.
Video enhancement is a local browser-rendered filter. Ambient Glow draws a small copy of the video on a local canvas. If you explicitly select Auto black bars, CinemaWide reads small, low-resolution pixel samples into local JavaScript memory to detect encoded borders. Sampling stops when that mode is disabled or the page is hidden; samples are not saved, encoded or uploaded. Inaccessible pixels leave the original framing available. On enabled YouTube pages it suppresses native ambient rendering without changing your saved YouTube Ambient mode preference; pausing CinemaWide restores that native rendering.
3. Preferences and temporary data
Global defaults, per-host overrides, audio preferences and keyboard shortcuts are kept in the extension's local browser storage. Hostnames for customised sites can therefore be part of your saved settings. Ordinary websites cannot read this extension storage. It is not uploaded or synced by CinemaWide.
Browser-session storage holds tab IDs, the last-focused tab, mute ownership and manual-unmute exceptions. Entries are removed as tabs close and session storage is cleared when the browser session ends. Group-opening records contain the source hostname/domain, group/window IDs and creation time. They are removed after initial navigation or tab closure; records older than two minutes are discarded when the group tracker next loads or handles a new opening. The last popup section and its interaction time are recalled for five minutes, without a website hostname, and then ignored.
Export saves a settings JSON file where you choose. Import reads only the file you select and replaces CinemaWide preferences. Uninstalling removes extension storage; exported files remain until you delete them.
4. Optional feedback
Only clicking Feedback opens the hosted form. Visiting that page makes a normal website connection; submitting it sends your email address, message and bot-verification token. No current website URL, browsing history, video, settings export or diagnostic report is attached automatically. You can use every viewing feature without submitting feedback. Please do not include passwords, private account details or other sensitive information.
Cloudflare hosts the form and provides Turnstile bot verification. It receives connection information, including IP address and browser information, to serve and protect the page. Resend delivers submissions to jabed098@gmail.com, hosted by Google Gmail. Your supplied email is an unverified reply address and is used to respond to your request. There is no autoresponder or mailing list.
The purpose is to handle feature requests, bugs and support, and to prevent abuse. Where UK data protection law applies, the basis is legitimate interests: providing support requested by users and protecting the service and inbox. Feedback is voluntary; email and message are required only if you choose to submit the form. Bot checks and rate limits can refuse delivery; they do not make decisions about your eligibility for the extension or its features.
5. Spam protection and retention
The server applies cooldowns, bot checks, duplicate protection and hard sending caps. The limiter stores keyed hashes of email/IP/message identifiers, counters and delivery status, rather than raw addresses or message contents. These hashes are pseudonymous security data, not a public list of submissions. Identifiers expire within 24 hours and are purged within a further 24 hours. Non-identifying monthly totals remain through the month and cleanup. Failed or uncertain deliveries consume capacity and are not automatically retried or queued.
Support correspondence remains in the developer's Gmail inbox only while needed to respond, investigate an issue or retain a necessary record of its resolution, and is then deleted unless needed for a legal obligation or dispute. You can request deletion at jabed098@gmail.com. Cloudflare, Resend and Google also process service/security records under their policies and account retention settings; those provider records may have different retention periods.
6. Providers and international processing
Feedback and connection data are shared with Cloudflare, Resend and Google for the purposes above. Those services may process data outside your country, including outside the UK/EEA. Their published privacy and data-processing terms describe their international-transfer safeguards and how to request information about them. No exclusively UK-hosted processing is promised.

Turnstile runs only on the hosted feedback website, never inside the extension. CinemaWide adds no analytics or advertising cookies. Turnstile may use security signals or browser storage under Cloudflare's terms. Websites and links you choose to visit make their usual requests under their own policies. Browser stores process installation and update activity under their own policies.
7. Your controls and rights
Use the toolbar popup to change preferences, pause CinemaWide on a site, turn off audio automation, or use your browser to disable/uninstall it. Turning off audio automation restores tabs CinemaWide muted while preserving manual mutes. Uninstalling cannot run cleanup code, so a tab left muted may need to be unmuted using the browser's tab control.
Depending on applicable law, you may request access, correction, deletion, restriction or portability of personal information, and object to processing based on legitimate interests. Some rights depend on the circumstances. Contact jabed098@gmail.com with a privacy request or complaint. The developer cannot remotely retrieve preferences stored only on your device. You can also complain to the UK's Information Commissioner's Office or your local data protection authority.
8. Policy changes
This page will be updated if CinemaWide's data practices change, with the date shown above. The same policy is bundled with the extension and available as a PDF.
