Terms of use

These terms apply to your use of https://do101.online (“DO101”). By using the site you agree to them. They are written to be readable rather than impressive; if something is unclear, ask on the contact page.

The service

DO101 provides free online tools, calculators and games. No account is required. Most tools run entirely inside your browser, as described on the privacy page.

Acceptable use

You agree not to:

• Use DO101 for anything unlawful, or to process content you have no right to process.
• Attempt to disrupt, overload or gain unauthorised access to the site or its endpoints.
• Scrape or automate the site in a way that degrades it for other people.
• Use the AI endpoint to attempt to bypass its limits, or resell access to it.

Your content

You keep all rights to whatever you put into a DO101 tool. For browser-based tools nothing is transmitted to us, so we neither receive nor store it. You are responsible for ensuring you are allowed to process the content you use.

Accuracy and disclaimers

DO101 is provided “as is” and “as available”, without warranties of any kind, whether express or implied, including any implied warranties of merchantability, fitness for a particular purpose and non-infringement.

The tools are built carefully and tested, but you should verify anything important. Specifically:

• Calculators are informational. The BMI calculator in particular is a rough screening tool and is not medical advice. Nothing on DO101 is medical, legal, financial or professional advice.
• Decoding is not verifying. The JWT decoder reads a token; it does not and cannot confirm that the token is authentic.
• Lossy conversion is lossy. Compressing or converting an image changes it. Keep your original.

Service availability

DO101 may change, suspend or discontinue any part of the site at any time, and does not promise uninterrupted availability. Typing Battle depends on a free third-party signalling service and on your network permitting peer-to-peer connections, so it may be unavailable in some conditions.

Third-party services

DO101 uses third-party services including its hosting provider, a public WebRTC signalling broker for Typing Battle, and — where configured — an AI model provider and Google AdSense. Those services have their own terms and privacy policies, and DO101 is not responsible for them.

Advertising

DO101 may display advertising to cover its costs. Ads are labelled and kept out of the way of the tools. DO101 does not endorse advertised products and is not responsible for third-party sites you reach through an advertisement.

Limitation of liability

To the maximum extent permitted by law, DO101 and its operator are not liable for any indirect, incidental, special or consequential damages, or for any loss of data, profits or goodwill, arising from your use of the site. Because DO101 is provided free of charge, total liability for any claim is limited to the amount you paid to use it, which is zero.

Nothing in these terms excludes liability that cannot lawfully be excluded, and some jurisdictions do not allow certain exclusions — in which case those exclusions do not apply to you.

Changes

These terms may be updated. The date at the top of the page shows when they last changed, and continuing to use DO101 after a change means you accept the updated terms.
