Operator
Sidenote is an open-source project maintained by Abhijith Warrier, an individual developer. The project is not a company, does not sell a product or subscription, and does not publish a company registration or VAT number because none applies.
The hosted app at sidenoteapp.vercel.app is operated by the maintainer. The website is hosted on GitHub Pages. A self-hosted Sidenote deployment is operated by whoever runs it.
Contact
For legal, privacy or security correspondence, use the private report channel. For general questions, open an issue at github.com/awbuilds/sidenote/issues.
A postal address is available on request through the private channel for formal legal correspondence. It is not published because the project is maintained by an individual.
Responsibility for content
The website describes the project and provides documentation. It is not professional advice (legal, financial, medical or otherwise). The software is provided under the AGPL-3.0 without warranty, as explained in the terms of use.
Links to third-party sites are provided for convenience. We do not control them and are not responsible for their content or practices.
Licence and source
The Sidenote code is licensed under the GNU Affero General Public License, version 3 only. The full text is in LICENSE. Because the app can be used over a network, the AGPL's source-offer applies: the source is linked from the app's Settings → About as well as from the repository.
Third-party libraries, fonts and artwork are listed with their licences in THIRD_PARTY_NOTICES.md.
Names and marks
The name “Sidenote”, the app icon and the original artwork are the project's marks. The AGPL licence covers the code, not the name or logo: do not use them in a way that suggests your fork or deployment is the official project. Third-party names and marks belong to their owners.
Jurisdiction
The project is maintained from India. These terms and any dispute relating to the website or hosted app are governed by Indian law, subject to any mandatory consumer protection that applies where you live. See the governing law section of the terms.
EU and UK users
If you are in the EU or UK, the GDPR or UK GDPR rights described in the privacy policy apply to any personal data we process. You can contact us through the private channel and complain to your local supervisory authority (in the UK, the ICO).
India
If you are in India, the Digital Personal Data Protection Act, 2023 applies to personal data we process. You may request access, correction or erasure, and raise a grievance through the private channel. The rights section of the privacy policy explains how.
Complaints
If you have a concern about the site, the hosted app or these notices, contact us first through the private channel so we can try to resolve it. Nothing here prevents you from contacting a regulator or court that has jurisdiction over the matter.
