Before protection starts

Protection stays off until you read the in-extension data notice and choose “Agree & enable” on this device. Agreement is stored locally and is not granted by browser sync. You can turn protection off at any time.

What the extension handles

Websites and page content

Scripts inspect page elements, visible text and consent controls to find cookie requests, distinguish access restrictions and identify supported ad placements. The current HTTP(S) tab URL and domain are used for the popup, site pauses and cookie cleanup. Browser network rules match request URLs against bundled lists. To recognize consent controls whose wording the bundled patterns do not cover, the short text labels of controls inside a detected consent dialog are passed to a classifier that is bundled with the extension and runs in its background on your device; the labels are not stored or sent anywhere. These URLs and page contents are not sent to the developer or stored as a browsing history. The extension does not capture keystrokes or deliberately extract passwords, messages or account details.

Cookies

Strict and Balanced query cookies applicable to the visited page and remove cookies whose names match the bundled tracker-name list. The browser API returns cookie objects, which may incidentally include other cookies and their values. The code uses names and scope metadata to decide what to remove; it does not read the value field, save cookie contents or transmit cookies. The browser's own cookie settings remain unchanged.

A local counter

One aggregate number of banners handled is saved in storage.local to display in the popup. No per-website counts, browsing URLs, visit timestamps or request log are persisted. The current tab's latest consent provider/action and handled count are held temporarily in memory, cleared on navigation, tab closure or background-worker restart.

Preferences and explicitly paused domains

Protection on/off, cookie profile, ad-block setting, onboarding completion and the domains you explicitly pause use browser storage.sync when available, with local storage as the fallback. Paused domains can reveal websites you use. When browser sync is enabled, the browser provider—for Chrome, Google—may transfer these settings between your signed-in devices under its sync settings and privacy policy. The developer does not receive this data. The aggregate counter and device agreement do not sync.

Your consent choices and websites

Strict and Balanced attempt to refuse optional cookies; Relaxed may choose acceptance if refusal is unavailable. Website controls may send your choice to the website or its consent provider using the website's own code. Those parties' policies apply to their processing. Hiding a banner does not record refusal or revoke an earlier choice. Protection cannot guarantee that every tracker is blocked or that a site honors refusal. The extension is not a way around subscriptions, logins or paywalls.

Sharing and Limited Use

The extension does not send browsing data, cookies, counters or page content to the developer, advertising platforms or analytics services. It does not sell data, build advertising profiles, use data for credit decisions or provide it for human review. Its use of information accessed through Google APIs complies with the Chrome Web Store User Data Policy, including the Limited Use requirements. Data is used only to provide the disclosed consent and blocking features. All scripts and filter lists are packaged with the extension; no remote code or filter subscriptions are downloaded.

Retention, deletion and your controls

The aggregate counter remains until you choose “Reset count” on the extension's Privacy & data page or uninstall the extension. There is no automatic expiry. Remove a pause by resuming protection for that site; the resulting change uses browser sync when available. Turn the main switch off to stop protection. Uninstalling removes the extension's local storage from that browser profile. Other devices and browser-provider sync copies are governed by the browser's sync controls; uninstalling one copy does not certify deletion everywhere. To clear synced preferences, remove or disable extension sync and manage the stored sync data through your browser account settings. We have no server copy to retrieve or delete.

Upgrading from an older local build removes legacy per-site statistics from local storage and removes the old synced statistics key, retaining only the aggregate count. Previously synced copies outside this browser cannot be independently verified as erased.

The policy page and support

The bundled policy works offline and includes no analytics, external fonts, forms or tracking scripts. A public copy will be hosted separately. Its hosting providers and any processing needed to deliver that website will be disclosed there. Opening a public policy page is separate from extension operation.

If you contact support, you choose what to send; your email service and the publisher's Gmail service process that communication so the publisher can respond. Do not send passwords, cookie values or private browsing information. The extension does not automatically attach diagnostics.

Filter list credits

The ad blocker's network rules include advertising domains adapted from EasyList by The EasyList authors, used under the Creative Commons Attribution-ShareAlike 3.0 license. The adapted list, rules/ads.json, is distributed under the same license. It is bundled when the extension is released and is not downloaded while you browse.

Terms of use

These terms apply to your use of Contego together with this privacy policy. By choosing “Agree & enable”, or by continuing to use the extension after an update that shows changed terms, you accept them. If you do not accept them, do not enable protection and uninstall the extension.

Automatic choices can be wrong

Contego acts on websites for you. It recognizes consent dialogs and their controls with bundled rules, text patterns and an on-device machine-learning classifier, and then clicks, hides or leaves them according to the profile you choose. These are automated estimates, not certainties. They can miss a refusal option, choose a different control than intended (for example open settings, save the preferences shown, dismiss a dialog or, in Relaxed, accept), misjudge whether a dialog asks for consent, payment, a subscription or a login, hide content that is not a cookie banner, or leave a dialog unhandled. Websites change their dialogs without notice. Check the choices that matter to you on the website itself, and pause protection or switch it off when a website does not work as expected.

No warranty

Contego is free software provided “as is” and “as available”, without warranties or conditions of any kind, express or implied, including warranties of merchantability, fitness for a particular purpose, accuracy, reliability, availability and non-infringement, to the fullest extent permitted by law. The publisher does not warrant that the extension will refuse, record or revoke consent correctly, that a website will receive or honor your choice, that tracking or advertising will be blocked, that websites will keep working, or that the extension will be free of errors or interruptions.

Your responsibility

You use Contego at your own risk and remain responsible for your consent choices and for how you use websites, including their terms. Contego is a personal browser tool. It is not legal advice, it does not make a website or an organisation compliant with any law, and it is not meant for managing consent on behalf of other people or for meeting legal obligations. Where a mistaken choice could harm you, make that choice yourself.

Limitation of liability

To the fullest extent permitted by applicable law, the publisher is not liable for any damage or loss arising from the use of, or the inability to use, Contego. This includes indirect, incidental, special and consequential damage; loss of data, access, content, revenue or opportunity; consent given, refused, recorded or not recorded on your behalf; choices made automatically or by mistake; content hidden or blocked; websites that stop working; and the acts of websites, consent providers and other third parties. Where liability cannot be excluded, it is limited to the amount you paid for the extension, which is nothing. Nothing in these terms limits liability that the law does not allow to be limited, such as liability for intent or gross negligence, or your mandatory rights as a consumer.

Third parties

Websites, their consent providers, filter-list authors and browser vendors are independent third parties. The publisher does not control and is not responsible for their content, consent tools, policies or availability, or for how they process your choices. Filter lists and recognition rules can contain errors or become outdated.

Changes and governing law

The dates above identify this policy and these terms. The publisher may change, suspend or discontinue Contego, this policy or these terms; updates arrive through your browser's extension store. Material changes to extension data practices or to these terms are shown in the extension before they apply, with renewed agreement where required. The public policy and the bundled copy describe the same released behavior. These terms are governed by the laws of Greece, without prejudice to the mandatory consumer-protection rules of your country of residence. If a provision is held invalid, the remaining provisions stay in effect.
