1. Scope and company information
This Privacy Policy describes how TankFlows, a digital commerce brand operated by Tianvex International Limited (“TankFlows”, “we”, “us” or “our”), collects, uses, shares and protects personal information when you visit our website, communicate with us, create an account where available, or use our digital product services.
Our services may connect customers with eSIM, mobile top-up, gift card, gaming and subscription products. Additional privacy notices may be presented where a particular product, partner or jurisdiction requires more specific information.
2. Information we collect
Information you provide
- Account information: name, email address, login credentials and account preferences, where account features are available.
- Order information: selected product, billing and transaction references, delivery details, country or region, and related order communications.
- Support information: the content of messages, attachments and other details you choose to provide when contacting us.
- Business enquiries: name, company, role and contact information submitted for partnership or commercial discussions.
Information collected automatically
When you use the website, we and our service providers may receive device and usage information such as IP address, browser type, device type, operating system, approximate location derived from IP, referring pages, pages viewed, timestamps, diagnostic information and cookie or similar technology identifiers. Optional collection is subject to your choices where required.
3. How we use information
We may use personal information to:
- provide, fulfil and electronically deliver digital products;
- create and manage accounts, authenticate access and maintain security;
- process transactions, reconcile payments and prevent fraud or abuse;
- respond to support requests and communicate service or order information;
- operate, maintain, troubleshoot and improve TankFlows;
- understand website performance and customer needs, subject to consent where applicable;
- comply with legal obligations, enforce terms and protect customers, TankFlows and others;
- send marketing communications where permitted and where you have provided any consent required by law.
Depending on applicable law, our legal bases may include performance of a contract, compliance with law, legitimate interests, protection of vital interests and consent.
4. Payment information handling
Payments may be handled by specialist payment processors. TankFlows may receive transaction status, payment method type, limited billing details and processor references, but does not intend to store complete payment card numbers or card security codes on this static website. Payment processors handle payment information under their own terms and privacy notices.
Do not send full card numbers, passwords or other sensitive credentials through the contact form or support email.
7. Retention and security
We retain personal information for as long as reasonably necessary for the purposes described above, including fulfilment, account management, dispute resolution, security, tax, accounting and legal compliance. Retention periods depend on the information and applicable requirements.
We use reasonable administrative, technical and organisational safeguards designed to protect personal information. No system or transmission is completely secure, so we cannot guarantee absolute security.
8. Your rights and choices
Depending on your location, you may have rights to request access, correction, deletion, restriction, portability or objection; withdraw consent; opt out of certain marketing; or complain to a data protection authority. These rights may be limited by law and may require identity verification.
To exercise a privacy right, email shop@tianvex.com with “Privacy Request” in the subject line and describe your request. We will respond as required by applicable law. You may also adjust cookie preferences through Cookie Settings.
Children
TankFlows is not directed to children who cannot legally consent to data processing or enter contracts in their jurisdiction. If you believe a child has provided personal information inappropriately, contact us.
9. Changes to this policy
We may update this Privacy Policy to reflect service, technology or legal changes. We will post the updated version here and revise the “Last updated” date. Where required, we will provide additional notice.
