Terms of Service

Welcome to BrainSync ("BrainSync", "we", "our", or "us"). These Terms of Service ("Terms") govern your access to and use of the BrainSync web application, Android app, and Chrome extension (collectively, the "Service"), available at brainsync.pro.

By creating an account or using the Service, you agree to these Terms. If you do not agree, do not use the Service.

1. Eligibility

You must be at least 13 years old to use the Service. If you are between 13 and the age of majority in your jurisdiction, you must have your parent or legal guardian's permission. By using the Service you represent that you meet these requirements.

2. Your Account

You are responsible for maintaining the confidentiality of your account credentials and for all activity that occurs under your account. Notify us immediately at support@brainsync.pro if you suspect unauthorised access.

3. Acceptable Use

You agree NOT to:

• Save, share, or generate content that is illegal, infringing, hateful, harassing, or sexually exploitative of minors
• Attempt to reverse-engineer, scrape, or stress-test the Service
• Use the Service to send unsolicited messages or spam
• Circumvent rate limits, AI quotas, or paywalls
• Resell, sublicense, or otherwise commercialise the Service without our written consent
• Submit content you don't have the right to share with our AI providers (Anthropic, OpenAI, Brave Search) for processing

We may suspend or terminate accounts that violate these rules without notice.

4. Your Content

You retain all ownership of the bookmarks, notes, categories, and other content you save ("Your Content"). By saving content to the Service, you grant BrainSync a worldwide, non-exclusive, royalty-free licence to host, store, process, and display Your Content solely to operate the Service and provide it to you and the people you choose to share it with.

If you make any of Your Content Public or Unlisted, you grant BrainSync the additional right to display it to anyone with the link or via search engines.

5. AI Processing

BrainSync sends Your Content to third-party AI providers (currently Anthropic, OpenAI, and Brave Search) to generate summaries, categories, transcriptions, and chat responses. Each provider operates under its own privacy policy and data-processing agreement. We do not permit these providers to train their models on Your Content.

AI outputs may occasionally be inaccurate, biased, or out-of-date. You are responsible for verifying anything important before acting on it.

6. Subscriptions & Payments

BrainSync offers a free tier with monthly AI usage limits and a paid BrainSync Plus subscription with higher quotas and additional features. Subscriptions are billed through Stripe and managed via RevenueCat. Pricing is shown in your local currency at checkout and includes applicable taxes where required.

Subscriptions auto-renew at the end of each billing period unless cancelled. You can cancel anytime from your Settings page or via the original payment processor. Refunds for unused time are at our discretion, except where required by law (e.g. EU 14-day cooling-off period).

7. Intellectual Property

The Service, including its design, code, branding, AI prompts, and aggregated analytics, is owned by BrainSync and protected by copyright, trademark, and other intellectual property laws. You may not copy, modify, or create derivative works from any part of the Service.

8. Termination

You may delete your account at any time from Settings → Danger Zone → Delete my account. We may suspend or terminate your account if you breach these Terms, if your account is inactive for an extended period, or if continued operation poses a legal or security risk.

9. Disclaimer of Warranties

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. BrainSync does not guarantee uninterrupted, error-free, or secure operation, nor that AI outputs will be accurate, current, or fit for any specific purpose.

10. Limitation of Liability

To the maximum extent permitted by law, BrainSync and its founders, employees, and contractors will not be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of profits, data, or business opportunities, arising from your use of the Service.

Our total liability for any claim relating to the Service will not exceed the greater of (a) the fees you paid us in the twelve months preceding the claim, or (b) US$50.

11. Changes to These Terms

We may update these Terms from time to time. When we do, we will revise the “Last updated” date above and, for material changes, notify you via email or an in-app notice. Continued use of the Service after changes take effect constitutes acceptance.

12. Governing Law & Disputes

These Terms are governed by the laws of Israel without regard to its conflict-of-laws rules. Disputes will be resolved in the competent courts of Tel Aviv, Israel, except where mandatory local consumer-protection law gives you the right to bring proceedings in your own jurisdiction.
