This Privacy Policy explains how K2Square LLC ("Superllink," "we," "us," or "our"), based in Portland, Oregon, USA, collects, uses, and protects information when you use the Superllink mobile app or website (superllink.com).
1. Information We Collect
We collect the following types of information:
- Account information: When you create a Superllink account, we collect your email address and password (stored securely, encrypted). You may also sign in using your Google account, in which case we receive basic profile information (name, email address) from Google, in accordance with your Google privacy settings.
- Top-up recipient information: Because Superllink lets you send mobile top-up/airtime credit to another person, we collect the recipient's phone number and any related details you provide to complete that transaction.
- Payment information: All payments are processed directly by PayPal. Superllink does not collect, store, or have access to your full credit/debit card numbers. PayPal's own privacy policy governs how they handle your payment details — see PayPal's Privacy Statement.
- Usage data: We may automatically collect basic technical information such as device type, app version, and general usage patterns to help us maintain and improve the service.
2. How We Use Your Information
- To create and manage your account
- To process and complete top-up transactions you request, including sending funds/credit to the recipient you specify
- To communicate with you about your account or transactions (e.g., confirmations, receipts, support)
- To maintain the security and integrity of our service
- To comply with applicable legal and regulatory obligations related to payment processing
3. Third-Party Services
Superllink relies on the following third parties to operate:
- PayPal — for processing all payments and top-up transactions
- Google Sign-In — for optional account authentication
- Mobile carriers / top-up providers — to deliver the mobile airtime/balance to the recipient you specify
These third parties have their own privacy policies governing how they handle information, and we encourage you to review them.
4. How We Share Information
We do not sell your personal information. We only share information as necessary to:
- Complete a transaction you've requested (e.g., sending your payment confirmation to PayPal, or transaction details to the top-up/mobile carrier network)
- Comply with a legal obligation, such as a court order or regulatory request
- Protect the rights, property, or safety of Superllink, our users, or others
5. Data Security
We take reasonable technical and organizational measures to protect your information, including encrypted password storage and secure connections (HTTPS). However, no method of transmission or storage is 100% secure, and we cannot guarantee absolute security.
6. Data Retention
We retain account and transaction information for as long as your account is active, or as needed to comply with legal, tax, or regulatory recordkeeping requirements related to financial transactions.
7. Your Rights and Choices
- You may access, update, or request deletion of your account information by contacting us (see below)
- You may stop using Google Sign-In at any time and use email/password login instead
- Depending on your location, you may have additional rights under applicable data protection laws
8. Children's Privacy
Superllink is not directed at children under 13, and we do not knowingly collect personal information from children under 13. If you believe a child has provided us with personal information, please contact us so we can delete it.
9. Changes to This Policy
We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated "Last updated" date.
