These Terms and Conditions ('Terms') constitute a legally binding agreement between you ('you', 'your', or 'User') and Carlos Eduardo Rührwiem ('we', 'us', or 'our'), concerning your access to and use of the https://www.inkundo.app website and the Ink Undo application (collectively, the 'Services').

By accessing or using our Services, you agree that you have read, understood, and agree to be bound by these Terms. If you do not agree with these Terms, you must discontinue use of the Services immediately.

We reserve the right to modify these Terms at any time. We will notify you of material changes by updating the 'Last updated' date above. Your continued use of the Services after such changes constitutes acceptance of the revised Terms.

2. DESCRIPTION OF SERVICES

Ink Undo is an AI-powered worksheet cleaning service that removes handwriting from scanned or photographed document images while preserving the original printed structure (grid lines, text, images). The Services allow you to:

• Upload images of completed worksheets (JPEG, PNG, WebP, HEIC formats, up to 20 MB per file)
• Process uploaded images using artificial intelligence to remove handwriting
• Download cleaned documents as PDF or PNG files
• Upload and process multi-page PDF documents

• Provide accurate and complete information associated with your Google account
• Maintain the security of your account credentials
• Accept responsibility for all activities that occur under your account
• Notify us immediately of any unauthorised use of your account

We reserve the right to suspend or terminate your account at our discretion if we believe you have violated these Terms.

4. CREDITS AND PAYMENT

The Services operate on a credit-based system. Each worksheet processing job consumes one credit (each page of a multi-page PDF consumes one credit). Credits are subject to the following terms:

5. PAYMENTS AND REFUNDS

All payments are processed securely through Stripe. By making a purchase, you agree to Stripe's Terms of Service.

• Currency: All prices are in EUR (Euros). Applicable taxes are calculated automatically.
• Refunds: Credit purchases are generally non-refundable. If a processing job fails due to a technical error on our end, the credit used for that job will be automatically refunded to your account.
• Chargebacks: If you initiate a chargeback or payment dispute, we reserve the right to suspend your account and deduct the corresponding credits.
