Terms of Service | ExtensionRadar

These terms govern your use of ExtensionRadar, a project that publishes daily Chrome extension rankings and growth charts. By using the ExtensionRadar website you accept these terms. They are written to be readable, because terms nobody reads protect nobody.

What ExtensionRadar provides

ExtensionRadar publishes charts of browser extension activity: newly published listings, young extensions gaining users, and older tools whose growth has recently accelerated. Every chart is built from dated observations of public Chrome Web Store signals, ranked by a published scoring method, and stamped with the exact dataset snapshot it was generated from. The service may evolve — additional platforms such as Firefox, richer histories, and research tooling — but the core contract stays the same: ExtensionRadar shows verifiable signals with their confidence labels attached.

The data is informational, not advice

Rankings on ExtensionRadar describe observed store signals. They are not install recommendations, security assessments, or investment advice. A high rank means an extension gained verified users inside a stated window — nothing more, and nothing less. Before installing anything, review the official Chrome Web Store listing, its permissions, and its reviews. ExtensionRadar deliberately does not rehost full descriptions, screenshots, or review text precisely so the store remains the source of truth. You use the charts to find candidates; you judge candidates yourself, with your own threat model and your own standards for what deserves a place in your browser.

No warranty on chart data

ExtensionRadar works hard to publish accurate growth data, and its methodology page documents the precision rules behind every number. Still, store data is self-reported by the platform, coverage is not exhaustive, and rounded badges stay rounded. All charts and figures are provided "as is" and "as available", without warranties of any kind, express or implied, including fitness for a particular purpose. If a number matters to a decision of consequence, verify it against the linked store listing — the same standard ExtensionRadar applies internally.

Intellectual property, attribution, and ExtensionRadar content

The ExtensionRadar name, logo, page design, scoring code, and written explanations belong to the project. Growth history data builds on public weekly datasets published by Extension Tracker and is used under Creative Commons Attribution 4.0, combined with ExtensionRadar's own observations; attribution appears in the site footer and the methodology page. Extension names, icons, and trademarks belong to their respective developers. Chrome is a trademark of Google, and Firefox is a trademark of Mozilla; ExtensionRadar is not affiliated with, endorsed by, or sponsored by either organization.

What ExtensionRadar content you may reuse

Quoting chart findings, embedding screenshots with credit, and linking to any page are all welcome — that is what the charts are for. What is not licensed is republishing the site wholesale as your own product or stripping confidence labels and observation windows from the numbers, because context is the part that makes growth data true.

Acceptable use

You are welcome to read, quote, and link to ExtensionRadar charts, including screenshots with credit. Automated access should stay polite: no scraping at rates that degrade the service, no republishing the full dataset as your own product, and no presenting ExtensionRadar charts under a name that implies Google or Mozilla produced them. It is fine to build tools that reference our pages; it is not fine to resell our data stripped of its confidence labels and observation windows, because that stripping is exactly what makes growth numbers misleading.

Ranking integrity

Rank order on ExtensionRadar is computed from data by the published scoring method. It is not for sale. If sponsored placements are ever introduced, they will be clearly labeled, visually separated from natural rankings, and documented on this site. Paid placement inside a natural ranking — buying a position that looks organic — will not happen on ExtensionRadar. If you are ever offered a better "natural" rank in exchange for payment, that offer did not come from this project, and we would like to hear about it.

Limitation of liability

To the maximum extent permitted by law, ExtensionRadar and its operator are not liable for indirect, incidental, special, consequential, or punitive damages, or for lost profits, revenue, or data, arising from your use of the site — including decisions made on the basis of chart data. Aggregate liability for any claim related to the service is limited to zero euros, reflecting that the service is provided free of charge as a research tool. Nothing in these terms limits liability where applicable law does not allow such limits.

Availability and changes

Charts update daily and occasionally fail; when they do, the last successful version is served with a staleness notice rather than an empty page. Features may be added, changed, or retired. These terms may also change; the "last updated" date will move with any revision, and continuing to use ExtensionRadar after a change means the revised terms apply. Material changes will be noted on this page in plain language.

Changes ExtensionRadar may make

Expect the catalog of charts to grow (new platforms, new windows, deeper histories) and expect the scoring method to evolve as better evidence arrives. Every such change ships with a version note on the methodology page, and historical charts keep the method they were built under — ExtensionRadar does not retroactively rewrite how a past ranking was computed, so citations of older charts stay meaningful over time.

How to reach the project

Questions about these terms, attribution, or ranking methodology can be raised through the public channels listed for the project, and substantive answers will be published rather than buried. Methodological questions are especially welcome — challenges to the scoring rules make the charts better, and the methodology page is the right place for that conversation to continue in the open.
