These Terms govern your use of Margin. Using it means you accept them.
These Terms of Service govern your access to and use of Margin, an open-source web annotation tool built on the AT Protocol, and the Margin Personal Data Server at margin.cafe (together, the "Service"), provided by Padding Labs LLC ("we", "us", "our"). By accessing or using the Service you agree to be bound by these Terms and by our Privacy Policy. If you do not agree, you must not use the Service.
Be 13 or older (16 in the EEA and UK), legally able to agree, and not on a sanctions list.
You must be at least 13 years of age to use the Service, or 16 if you reside in the European Economic Area, the United Kingdom, or another jurisdiction with a higher age of digital consent. You must have the legal capacity to enter into a binding agreement. You represent that you are not located in a country subject to comprehensive United States sanctions and that you are not on a U.S. government list of restricted parties.
You own your content. Notes are public by default and we cannot recall federated copies.
You retain all ownership rights in the content you submit through the Service ("User Content"). You grant us a worldwide, non-exclusive, royalty-free licence to host, store, reproduce, transmit, index, generate vector representations of, and display User Content as necessary to operate the Service. This licence terminates when you remove the relevant User Content, save for retention required by law, retention in routine backups for a reasonable period, and copies already disseminated to third parties via the AT Protocol that are outside our control.
Records you publish through the AT Protocol are public by default and may be retrieved, copied, indexed, and re-displayed by any third party. Removal from your Personal Data Server does not guarantee removal from such third parties. You are solely responsible for User Content and represent that you hold all rights necessary to publish it.
Do not break the law or harm other users.
You agree not to use the Service to:
We may remove content or accounts for violations. You may appeal.
You may discontinue use of the Service at any time. We may suspend or terminate your access, or remove specific User Content, where we reasonably determine that you have breached these Terms, the law requires us to do so, or such action is necessary to protect users or third parties. Where we take such action, and unless prohibited by law, we will provide a statement of reasons. You may appeal by replying to the relevant notice or by writing to [email protected] within six months.
Send a properly-formed DMCA notice if your copyright is infringed.
We respond to notices that comply with the U.S. Digital Millennium Copyright Act. If you believe content on the Service infringes your copyright, send a notice containing the elements required by 17 U.S.C. § 512(c)(3) to [email protected] with the subject line "DMCA Notice". Knowingly false notices may give rise to liability under § 512(f). We terminate the accounts of repeat infringers.
Provided "as is". Aggregate liability capped at US$50. Mandatory protections still apply.
To the maximum extent permitted by law, the Service is provided "as is" and "as available", without warranties of any kind, express or implied, including merchantability, fitness for a particular purpose, and non-infringement. We do not warrant that the Service will be uninterrupted, secure, or free from defects.
To the maximum extent permitted by law, we shall not be liable for any indirect, incidental, special, consequential, or punitive damages, or for loss of profits, revenue, goodwill, or data. Our aggregate liability arising out of or relating to the Service shall not exceed the greater of fifty United States dollars (US$50) or the amount you paid us during the twelve months preceding the event giving rise to the claim.
Nothing in these Terms excludes or limits liability that cannot be excluded or limited under applicable law, including liability for fraud, gross negligence, wilful misconduct, or death or personal injury caused by negligence.
If your conduct or content gives rise to a claim against us, you cover our costs.
To the extent permitted by law, you shall indemnify, defend, and hold us harmless from any third-party claim, demand, or proceeding arising out of your User Content, your use of the Service, or your breach of these Terms or applicable law. This obligation does not apply where prohibited by mandatory consumer-protection law.
Wyoming law applies. We give notice of material changes.
These Terms are governed by the laws of the State of Wyoming, without regard to its conflict-of-laws rules. The state and federal courts located in Sheridan County, Wyoming shall have exclusive jurisdiction over any dispute, save where mandatory consumer-protection law in your country of residence provides otherwise. Before commencing any claim, you agree to contact us at [email protected] and to attempt to resolve the matter informally for a period of sixty days.
We may amend these Terms from time to time. We will provide at least thirty days' notice of any material change by in-product notice or, where applicable, by email. If any provision is held unenforceable, the remainder of these Terms shall continue in full force and effect. We may assign these Terms in connection with a merger, acquisition, reorganisation, or sale.
