1. Acceptance of Terms

These Terms of Service ("Terms") constitute a legally binding agreement between you ("User", "you", or "your") and the operators and contributors of SideNote ("SideNote", "we", "us", or "our"). By downloading, installing, accessing, or using the SideNote Chrome Extension or visiting this website, you confirm that you have read, understood, and agreed to be bound by these Terms and our accompanying Privacy Policy.

2. Description of Service & Features

SideNote is a productivity browser extension engineered for Chromium-based browsers that provides local-first note-taking and voice memo recording directly within Google Chrome's native side panel. The Service includes, without limitation:

  • Side Panel Workspace (sidepanel.html): A dockable, non-intrusive container displaying notes, audio controls, and rich text editors alongside active web tabs.

  • Google Keep Color Palettes: Authentic pastel palettes (Sand, Mint, Storm, Coral, Dusk) for organizing and prioritizing your notes.
  • Voice Memo Recording & Playback: In-browser audio recording utilizing the Web Audio API (getUserMedia) with integrated waveform visualization and local playback.
  • All-Notes Masonry Dashboard (all-notes.html): A multi-column visual manager for searching, filtering, and organizing notes across all visited domains.
  • Universal Note Exports (Pro): Exporting notes into Markdown (.md), clean HTML, CSV, or structured JSON formats for interoperability with external knowledge tools.
  • Full Data Backup & Restore (Pro): Creating and downloading complete JSON backups of all stored notes, audio attachments, and configuration metadata.
  • Google Identity & Customer Portal: Optional Google OAuth2 sign-in to link Pro licenses and direct access to the Polar Customer Portal for subscription management.
  • Settings & Diagnostics (settings.html): Microphone diagnostics, storage quota metrics, and personalization preferences.

3. License Grant & Restrictions

Subject to your compliance with these Terms, SideNote grants you a personal, worldwide, revocable, non-exclusive, non-transferable, and non-sublicensable license to install and use the SideNote Chrome Extension on supported devices.

Restrictions:

You agree that you will not:

  • Modify, adapt, translate, reverse engineer, decompile, or disassemble any portion of the software, except to the extent permitted by applicable open-source licenses or mandatory law.
  • Circumvent or disable any security features, licensing mechanisms, or protocol restrictions built into the extension.
  • Re-distribute, sublicense, or sell the software as a standalone commercial product without explicit written consent.
  • Use SideNote in any manner that could interfere with, disrupt, negatively affect, or inhibit other users or compromise browser integrity.

4. User Content & Intellectual Property Ownership

100% User Ownership of Notes & Recordings:

You retain sole and exclusive ownership of all text, rich notes, audio voice recordings, images, tags, and annotations created, recorded, or saved by you within SideNote ("User Content"). SideNote claims NO copyright, proprietary interest, or license over your User Content. Because your content resides in your local browser storage, we do not view, analyze, access, or utilize your User Content.

SideNote Intellectual Property: All software code, visual designs, trademarks, service marks, graphics, and documentation associated with SideNote are the exclusive property of SideNote and its licensors, protected by copyright, trademark, and other applicable intellectual property laws.

5. Acceptable Use & Recording Consent Compliance

You are solely responsible for your conduct while using SideNote:

  • Lawful Use: You agree to use SideNote only for lawful purposes and in accordance with all applicable local, national, and international laws, regulations, and third-party terms of service.
  • Audio Recording Compliance: When utilizing the voice memo recording feature to record conversations, lectures, or meetings, you are solely responsible for complying with all applicable wiretapping and audio recording consent laws (including one-party or all-party consent statutory requirements in your jurisdiction). SideNote disclaims all liability for unauthorized audio recording by users.
  • Third-Party Copyrights: When taking notes on third-party web content, you are responsible for respecting third-party copyrights and intellectual property rights under applicable fair use or fair dealing doctrines.

6. Local-First Architecture & Data Disclaimer

DATA STORAGE NOTICE:

SideNote is a local-first application that stores notes and voice memos within your browser's local sandbox (chrome.storage.local). We do not maintain remote cloud copies of your data on external servers.

Because storage is local, clearing your browser profile, uninstalling the extension, or hardware damage will remove locally cached data. SideNote shall have no liability for data loss arising from local browser cache purges or system failures.

7. Subscriptions, Lifetime Licenses & Polar Billing

SideNote provides free local note-taking functionality alongside optional paid upgrade tiers (Pro Monthly, Pro Annual, Lifetime License) that unlock universal exports and data backup capabilities:

• Free Tier: Core features including side panel notes, TipTap rich text, Google Keep tonal colors, up to 10 audio memos per note, and the All-Notes dashboard are free without fees or mandatory account creation.

• Paid Upgrade Plans: Users may purchase a Pro Monthly subscription ($3.99/month), Pro Annual subscription ($29.99/year), or Lifetime License ($49.99 one-time). Pricing is inclusive of applicable taxes unless specified otherwise at checkout.

• Merchant of Record & Payment Processing: All billing, invoicing, taxation, and checkout workflows are operated by our Merchant of Record, Polar (polar.sh). By initiating a transaction, you agree to Polar's terms and privacy policies. SideNote does not store or process your credit card numbers.

• Automatic Renewal: Monthly and Annual subscriptions renew automatically at the expiration of each billing cycle unless cancelled prior to the renewal date. Lifetime Licenses represent a single one-time payment with no recurring charges.

• Cancellation & Self-Service Portal: You may cancel recurring subscriptions at any time via the Polar Customer Portal, accessible directly from the extension user menu or settings. Upon cancellation, your Pro access continues through the conclusion of your active billing period, after which your account reverts to the Free tier with no loss of local notes.
