Terms of Use
Last updated: March 14, 2026
1. Acceptance of Terms
By downloading, installing, or using the Nexio mobile application (the “App”), you agree to be bound by these Terms of Use. If you do not agree with any part of these terms, you must not use the App.
2. Description of Service
Nexio is an AI-powered business card scanner application that allows users to photograph business cards and receive extracted contact information, including names, phone numbers, emails, company names, job titles, and addresses. The App is provided by Masteret Labs.
3. User Accounts
You may use the App anonymously with limited functionality, or create an account using Apple Sign-In or Google Sign-In to enable cloud sync and full features. You are responsible for maintaining the security of your account.
4. AI-Generated Content
Contact information extracted from business cards is generated by artificial intelligence and is provided for informational purposes only. Results may not always be accurate.
- Always verify extracted contact details before relying on them for important business communications.
- Masteret Labs is not liable for any harm or loss arising from inaccurate AI-generated contact data.
5. Subscriptions
5.1 Free Tier
Free users receive a limited number of scans per period. Scan quotas refresh periodically as described in the App.
5.2 Nexio Pro
Nexio Pro is an auto-renewable subscription that provides unlimited business card scans and premium features. Payment is charged to your Apple App Store account at confirmation of purchase.
- Subscriptions automatically renew unless canceled at least 24 hours before the end of the current billing period.
- Your account will be charged for renewal within 24 hours before the end of the current period.
- You can manage and cancel subscriptions in your App Store account settings.
- Any unused portion of a free trial period will be forfeited when you purchase a subscription.
6. Fair Usage Policy
Nexio Pro provides generous access to scanning and processing features. To maintain service quality and fair access for all users, the following fair usage guidelines apply:
- Scan volume: Premium subscribers may perform up to 500 scans per day and 5,000 scans per calendar month under normal usage. Volumes significantly exceeding these thresholds may be subject to temporary rate limiting.
- Rate limiting: To protect our infrastructure, scans are limited to 10 per minute. Requests exceeding this rate will be queued automatically.
- Automated usage: The App is designed for individual, human-initiated scans. Automated, scripted, or bot-driven scanning is prohibited.
- Resale: Using the App to provide scanning services to third parties on a commercial basis without prior written consent from Masteret Labs is prohibited.
Users who consistently exceed fair usage limits will be contacted before any action is taken, except in cases of clear abuse as defined in Section 8.
7. User Content
You retain ownership of all photos you upload. By using the App, you grant Masteret Labs a limited license to process your photos for the purpose of contact extraction. We do not use your photos for advertising, marketing, or any purpose other than providing the App service.
8. Account Termination & Abuse
8.1 Termination by User
You may stop using the App at any time and cancel your subscription through Apple’s subscription management settings.

We reserve the right to suspend or terminate your account and subscription, with or without notice, if we reasonably determine that:
- You have violated these Terms of Use, including the Fair Usage Policy.
- Your usage pattern indicates abuse, including but not limited to: an unusually high volume of API calls within a short time frame, automated or scripted access, or any activity that places excessive burden on our systems.
- You are using the App for any unlawful or fraudulent purpose.
- You are reverse-engineering, scraping, or attempting to extract data from our AI models or infrastructure.
8.3 Refunds Upon Termination
If your account is terminated by Masteret Labs due to abuse or violation of these Terms, we may, at our sole discretion, issue a pro-rata refund for the remaining unused portion of your current billing period via Apple’s refund process. Refunds are not guaranteed and are evaluated on a case-by-case basis.

- Use automated tools, scripts, or bots to interact with the App
10. Disclaimer of Warranties
The App is provided “as is” and “as available” without warranties of any kind, either express or implied. We do not guarantee the accuracy, completeness, or reliability of any contact information extracted from business cards.
11. Limitation of Liability
To the maximum extent permitted by law, Masteret Labs shall not be liable for any indirect, incidental, special, consequential, or punitive damages arising from your use of the App. Our total liability shall not exceed the amount you paid for the App in the twelve months preceding the claim.
