   By using our Services, you agree to this Policy. If you do not agree, please do not use the Services.

0) Service Scope (Consumer Personal Use Only)

SimBuster is designed for personal communications with your known contacts. We do not support business, commercial, marketing, or promotional messaging/calling. We do not provide an API or automation features; every message must be composed and sent manually by a user in the app.

1) Age Requirement

You must be 18+, or 13+ with parental/guardian consent. Children under 13 may not use the Services.

2) Information We Collect

We collect information to operate, secure, and improve the Services. What we collect depends on how you use SimBuster.

2.1 Information You Provide

  • Account & Verification. To create an account you provide a mobile number (used for sign‑in and verification via SMS or call‑back PIN). You may also provide email, name, and country for account recovery, receipts, and support.

  • Contacts (optional). If you grant permission, we read phone numbers (not contact names) from your device to discover contacts you can call/message via SimBuster.

  • Profiles. For virtual numbers you may add a profile name and optional profile picture.

  • Payments. If you purchase Paid Services, payments are processed by trusted providers (e.g., Apple/Google in‑app purchase, PayPal, CardStream). Card data is handled by the provider; we receive receipts/transaction identifiers and billing details (e.g., billing name/address and email) to apply taxes, provide invoices, and prevent fraud.

  • Support. If you contact support, we collect the details you provide (account number, email, device info, and description of the issue).

2.2 Information We Collect Automatically

  • Call History. We store time, originating number, recipient number(s), and duration for voice/video calls to provide call history, billing (where applicable), quality assurance, and to meet regulatory requirements. You can delete your in‑app call history; underlying billing/regulatory records may persist for required periods.

  • Messages.

    • Chat (app‑to‑app): Stored to sync across devices; you can delete chat threads in the app.

    • SMS/MMS to phone numbers: Stored to deliver and sync; you can delete message content in the app. We retain time, originating number, recipient number, and message parts for billing and compliance.

  • Device & App Data. Device model, OS, app version, browser info (web), language, and IP address to help with troubleshooting, security, localisation, and abuse prevention.

  • Diagnostics & Logs. Connection logs, crash reports, performance metrics kept for a limited period to operate and improve the Service.

  • Cookies & Analytics. Our website/app may use cookies and tools like Google Analytics to remember preferences and understand usage. You can control cookies via your browser; disabling some cookies may affect functionality.

2.3 Online Analytics & Ads

  • We use analytics to understand usage and improve the Service. We do not use or share your personal data for cross‑context behavioral advertising. You can control cookies via your browser settings.

3) How We Use Information

  • Provide the Service. Operate accounts, connect calls/messages, allocate numbers, and maintain your history across devices.

  • Billing & Taxes. Process payments, apply taxes, issue invoices, and combat fraud/chargeback abuse.

  • Support & Communication. Respond to requests; send important service messages (e.g., security alerts, plan/renewal notices). Marketing is sent only where permitted or with your consent and can be withdrawn at any time.

  • Safety & Security. Monitor for spam, fraud, and abuse; enforce our Terms & Conditions and carrier policies.

  • Improve the Service. Fix bugs, measure performance, and develop new features.

  • Legal/Compliance. Meet regulatory and lawful‑request obligations.

  • Consumer use only. We do not support business/commercial messaging and we do not send messages in bulk or on behalf of businesses.

  • No API/automation. We do not provide an API; all communications must be manually initiated by you in the app.

Calling & Messaging: When you communicate, your caller ID/virtual number and message content are shared with recipients and the networks used to complete communications.

4) When We Share Information

We do not sell personal data. We share only as needed to operate the Services:

  • Service Providers & Carriers. With telecommunications carriers/aggregators, cloud hosting, payments, anti‑fraud/abuse prevention, analytics, and support tools—limited to what’s necessary under contracts and safeguards.

  • Legal. To comply with laws, regulations, lawful requests, or to protect rights, safety, and property of users, us, or others.

  • Business Transfers. If we undergo a merger, acquisition, or asset sale, data may transfer to the new owner under this Policy or a successor policy with comparable protections.

  • With Your Direction. For example, when you port a number or connect to third‑party services.

5) How Long We Keep Information

We keep personal data only as long as necessary for the purposes above, including legal/regulatory retention. Typical examples:

  • Billing/Regulatory records: kept for required periods (varies by country).

  • Diagnostics logs: short retention for operations.

  • Message content (chat/SMS): you can delete in the app; related delivery/billing metadata may remain for legal/regulatory needs.

  • Account data: retained while your account is active; deleted or anonymised after closure unless legally required to retain it.

6) Your Choices & Rights

Your rights depend on your location and applicable law (e.g., UK GDPR/EU GDPR, Hong Kong PDPO, and similar laws). Subject to conditions and exemptions, you may have rights to:

  • Access your personal data.

  • Correct inaccurate data.

  • Delete/erase your data.

  • Restrict or object to processing in certain circumstances.

  • Portability of certain data.

7) Legal Bases (if you are in the UK/EEA)

We process personal data on the following bases:

  • Contract: to provide the Services under our Terms & Conditions.

  • Legitimate Interests: to operate a reliable, secure telecom service; prevent fraud/abuse; improve features—balanced against your rights.

  • Vital Interests/Public Task: where required to protect life/safety or comply with applicable law.

8) International Data Transfers

We may process information in Hong Kong, the UK/EEA, the US, and other countries. Where required, we use appropriate transfer mechanisms (e.g., Standard Contractual Clauses or equivalent) and safeguards.

9) Data Security

We use technical and organisational measures such as encryption in transit, access controls, network and application monitoring, and vendor due diligence. No system is 100% secure; keep your device and account credentials safe and notify us immediately if you suspect unauthorised access.

10) Porting, Retention & Regulatory Notes

  • Number Porting. If you request to port a number, we will share necessary data with the gaining/losing provider to complete the port.

  • Lawful Requests. We may preserve and disclose information in response to lawful requests (e.g., court orders, warrants) consistent with applicable law.

11) Children’s Data

SimBuster is not intended for children under 13 and we do not knowingly collect data from them. If we learn that we have collected such data, we will delete it.

12) Region‑Specific Information

  • UK/EU Users. You may contact your local supervisory authority (the UK Information Commissioner’s Office) if you are concerned about our handling of personal data. We will work with you to resolve any concerns.

  • Hong Kong Users. You may contact the Privacy Commissioner for Personal Data (PCPD) if you have unresolved concerns under the Personal Data (Privacy) Ordinance.

  • California (if applicable). Where the California Consumer Privacy Act/CPRA applies, you may request access/deletion and opt‑out of sale/sharing (we do not sell personal data). Use the contact methods above to exercise these rights.

13) Changes to This Policy

We may update this Policy from time to time. If changes are material, we will notify you via the app, website, or email. The “Effective date” above shows when it last changed.
