Crono ("the Service") is a free, browser-based chronometer for timing small and in-house sport competitions, operated by the Crono project ("the operator", "we", "us"). By accepting these Terms & Conditions and by using the Service, you agree to be bound by them. If you do not agree, please do not use the Service.
Crono runs entirely in your web browser. It lets you set a start time, record finish times, optionally import or enter a list of participants, organise results into rankings and export them as a CSV file. All processing happens on your device; the Service does not require an account and does not send your timing data to any server.
The Service is provided "as is" and "as available", without warranties of any kind, whether express or implied, including but not limited to fitness for a particular purpose, accuracy or uninterrupted availability.
Recorded times depend on your device's clock, your browser and your own input, and may contain errors or delays. The Service is not intended for official, certified or safety-critical timing. You are responsible for independently verifying any result before relying on it. Do not use Crono as the sole source of truth for an official competition without an appropriate backup method.
The Service stores your data locally in your browser (see the Privacy Policy for details). The operator has no access to this data and cannot recover it for you. You are solely responsible for the data you enter and for backing it up.
Crono is an open-source project. Its source code is made available under the licence included in the project's repository, and your use of the code is subject to that licence. Trademarks or names of third parties referenced in the Service belong to their respective owners.
To the maximum extent permitted by applicable law, the operator and contributors shall not be liable for any direct, indirect, incidental, special or consequential damages, or for any loss of data, results or profits, arising out of or in connection with your use of, or inability to use, the Service — including any inaccuracy of recorded times. Your sole remedy if you are dissatisfied with the Service is to stop using it.
The Service may change or be discontinued at any time without notice. These Terms may be updated from time to time; the "Last updated" date above reflects the latest version. If the changes are material, you may be asked to accept the updated Terms again. Continued use after an update means you accept the revised Terms.
These Terms are governed by the laws applicable in the operator's country of residence, without regard to conflict-of-law rules. Nothing in these Terms limits any mandatory consumer rights you may have under your local law.
Questions about these Terms can be raised through the project's repository at github.com/george-run/crono.
Crono ("the Service"), operated by the Crono project ("the operator"), is a free chronometer that runs entirely in your web browser. It is designed to be privacy-friendly: it does not use tracking, advertising or analytics cookies, it does not create user accounts, and it does not send your timing data to any server. This policy explains what is stored and where.
To work, Crono saves information locally in your browser's storage (the localStorage mechanism). This data stays on your device and is not transmitted to the operator or to any third party — unless you turn on the optional results webhook described below. It includes:
This storage is strictly functional — it is what makes the app usable — and is not used to profile or track you.
The Service does not load advertising, does not use analytics or tracking cookies, and does not build any profile of you. No third-party marketing scripts are included.
The Service is published as static files via GitHub Pages. Like any website, when your browser requests the page, the hosting provider (GitHub) may process technical connection data such as your IP address and user-agent in its server logs in order to deliver the site. This processing is carried out by the hosting provider under its own terms; the operator of Crono does not maintain its own server logs of your activity. The Service also loads its web fonts from Google Fonts, so your browser contacts Google's servers (which may receive your IP address) to download them; no analytics, advertising or tracking scripts are used.
Optional results webhook. Crono can optionally send your results to a web address (a "webhook") that you configure yourself in Options. This is off by default — nothing is sent unless you enter a URL. When enabled, the results (start time, finish times and any participant names/categories you added) are sent as JSON to that address whenever results change. The destination is your choice and under your control; you are responsible for that endpoint. Clear the field to turn it off and keep everything on your device.
If you import or enter details about participants (such as names or year of birth), that information is stored only on your device, under your control. You are responsible for having a lawful basis to process it and for handling it in accordance with any applicable data-protection laws. The operator never receives this information.
You can delete recorded results at any time with the in-app "Clear results" action, and you can remove all stored data by clearing your browser's site data for this page. Because the data lives only in your browser, the operator cannot access, export or delete it on your behalf. Export to CSV if you want to keep a copy.
The Service is a general-purpose timing tool and is not directed at children. It does not knowingly collect personal data from anyone, since no data leaves your device.
This policy may be updated from time to time. The "Last updated" date above reflects the latest version. If changes are material, you may be asked to review and accept the updated documents again.
Questions about privacy can be raised through the project's repository at github.com/george-run/crono.
Paste a webhook URL and Crono will POST the results as JSON — instantly when they change and re-synced every 5 seconds, so the other system stays live. It needs a connection; leave it empty to keep everything on this device.
Your endpoint must accept a cross-origin POST: answer the browser's preflight (OPTIONS) and return the headers Access-Control-Allow-Origin (your site or *), Access-Control-Allow-Methods: POST, OPTIONS and Access-Control-Allow-Headers: Content-Type. The body is JSON (Content-Type: application/json) over HTTPS.
