Terms of Service
Effective date: 2026-09-28 · Applies to Accrue Notes for iOS, Android, and macOS
Welcome to Accrue Notes. By downloading, installing, or using the application, you agree to be bound by these Terms of Service ("Terms"). In this document, "we", "us", or "our" refers to the developer of Accrue Notes, and "you" refers to the user.
1. Licence
We grant you a personal, revocable, non-transferable, non-exclusive licence to install and use Accrue Notes on devices you own or control. You may not reverse-engineer, decompile, or modify the app, extract or redistribute its built-in algorithms, graph visualizers, or templates, or attempt to circumvent in-app purchase validation mechanisms.
2. Accounts and Data Ownership
Accrue Notes operates on a local-first philosophy with no centralized accounts. All notes, bi-directional links, knowledge graphs, and mental models you create belong exclusively to you, and 100% of your data remains on your local device. Safe-keeping, backups, and data exports are your sole responsibility. Uninstalling the app permanently erases local sandbox data; please export your backups before reinstalling or switching devices. See our Privacy Policy for full details.
3. Paid Items and Pro Monthly Subscription
- Accrue Notes Pro (Monthly Subscription): An auto-renewing subscription priced at $2.99/month or $24.99/year (or equivalent tier in your local store currency and taxes). Subscribing unlocks unlimited notes beyond the 50-note limit, advanced neural knowledge graphs, unlimited AI deep analysis, all 6 premium knowledge packs, private iCloud/WebDAV sync, and academic-grade exports.
- Billing Cycle and Auto-Renewal: The subscription period is 1 month. Payment will be charged to your store account (Apple ID, Google Account, or Huawei ID) at confirmation of purchase. Your account will be charged for renewal within 24 hours prior to the end of the current monthly period.
- Cancel Anytime: You can cancel anytime without penalty. To cancel renewal, turn off auto-renew in your device system settings ("Settings → Account → Subscriptions") at least 24 hours before the end of the current billing cycle. After cancellation, Pro benefits remain active until the end of the paid period, then revert to the free plan. All your existing local notes and data remain completely intact.
- Restore and Refunds: To restore an active subscription on a new device, tap "Restore Purchases" in the app. Billing, refunds, and invoices are handled directly by the respective app store in accordance with their consumer terms.
4. AI Features With Your Own API Key (BYOK)
- AI cognitive mirroring and deep research run via Bring Your Own Key (BYOK). You configure your own API key with a third-party LLM provider. Your legal relationship, terms of use, and API fees are strictly between you and that provider; all API token usage costs are your responsibility;
- Network requests are sent directly from your device to the official endpoint of your provider without intermediary servers;
- AI responses and research reports are generated automatically for reference only and do not constitute legal, medical, financial, or investment advice. Large language models may produce inaccurate content or hallucinations; verifying and acting upon outputs is your sole judgement.
5. User Generated Content
You retain complete intellectual property rights to all notes, formulas, images, sketches, and thoughts entered into the application. You represent and warrant that you hold all necessary rights to your content and will not use the app for unlawful activities.
6. Open Source and Third-Party Assets
Accrue Notes utilizes open-source components including the KaTeX mathematical typography library. Applicable open-source licenses (MIT, Apache 2.0, BSD) and attributions are available inside the application under "Settings → About".
7. Disclaimers and Limitation of Liability
Accrue Notes is provided on an "as-is" and "as-available" basis. To the maximum extent permitted by law:
- We are not liable for any data loss resulting from hardware failure, operating system updates, accidental deletion, or failure to export regular backups;
- We make no warranties regarding the availability, latency, or accuracy of third-party AI provider endpoints;
- Under no circumstances shall the developer be liable for indirect, incidental, consequential, or punitive damages. Our total liability is strictly limited to the amount you actually paid for Accrue Notes.
8. Modifications and Service Continuity
We may periodically update, enhance, or adjust application features. Active Pro subscription benefits are guaranteed for the paid period. Even if online maintenance ceases in the future, installed versions of Accrue Notes will continue to operate offline indefinitely with local notes and export functionality preserved.
9. Governing Law
These Terms shall be governed by and construed in accordance with the laws of the developer's jurisdiction, without regard to conflict of law principles. Mandatory consumer protection laws in your jurisdiction remain unaffected.
10. Changes and Contact
If these Terms are modified, the updated version will be published on our website and in app update notes. Continued use signifies acceptance of the updated Terms. For inquiries, contact:
