1. Scope

This Privacy Policy applies to visitors, customers, account holders, business contacts, support requestors, and prospective users globally. Telzen is not a Bangladesh-only service and may offer products to residents of multiple countries, subject to legal and operational availability.

2. Data collected

Telzen may collect the following categories of information:

• Identity data, such as name, email address, billing name, business name, and support identity information.
• Contact data, such as phone number, email address, shipping address, and country.
• Account data, such as login credentials, account preferences, order history, and support history.
• Device and technical data, such as device model, operating system, browser type, IP address, eSIM compatibility indicators, activation metadata, app diagnostics, cookies, and usage logs.
• Transaction data, such as payment amount, currency, gateway reference, card metadata tokens supplied by processors, invoice data, refund history, fraud-screening results, and tax-related information.
• Connectivity and provisioning data, such as ICCID, eSIM activation status, QR code fulfillment status, destination country, plan type, plan validity, data balance events, and provider-issued identifiers needed to activate or support the service.
• Compliance data, such as information provided for sanctions screening, chargeback defense, anti-fraud reviews, export-control checks, and lawful requests from authorities where required by law.

Telzen does not intentionally collect unnecessary sensitive data and requests only the minimum information reasonably necessary to process orders, reduce fraud, deliver products, support customers, and comply with law.

3. How data is used

Telzen may use personal data to:

• Create and manage user accounts.
• Process orders, payments, refunds, exchanges, and support requests.
• Provision and deliver data-only eSIMs and physical SIM orders through third-party suppliers.
• Verify compatibility, troubleshoot service issues, and confirm activation status.
• Personalize language, destination, currency, and product presentation.
• Detect fraud, abuse, sanctions risk, suspicious transactions, or policy violations.
• Comply with tax, accounting, payment, audit, export-control, and legal obligations.
• Improve website performance, marketing effectiveness, product quality, and customer experience.

4. Legal bases

Where applicable law requires a legal basis, Telzen processes personal data based on one or more of the following: performance of a contract, compliance with legal obligations, legitimate business interests, fraud prevention, security protection, and consent where required for certain cookies or marketing communications.

5. Sharing of data

Telzen may share personal data with:

• Third-party connectivity providers, eSIM aggregators, provisioning partners, and underlying network-related vendors to enable service delivery.
• Payment processors, banks, local gateways, card networks, fraud-screening providers, and accounting or tax service providers to process transactions and meet compliance obligations.
• Shipment, warehousing, and fulfillment providers for physical SIM delivery.
• Cloud hosting, analytics, customer support, CRM, communication, and security vendors.
• Legal, regulatory, tax, law-enforcement, or judicial authorities where disclosure is required by law or reasonably necessary to protect rights or prevent fraud.

Telzen does not sell personal data in exchange for cash consideration. Data is shared only as needed to run the service, complete transactions, prevent fraud, provide support, or satisfy legal obligations.

6. International transfers

Because Telzen serves customers globally and uses international service providers, personal data may be processed in Bangladesh and in other countries where its vendors, processors, partners, or infrastructure providers operate. Telzen takes reasonable contractual and operational steps to protect data during international transfer, taking into account the sensitivity of the information and the jurisdictions involved.

7. Cookies and analytics

Telzen may use cookies, SDKs, pixels, and similar technologies to remember user settings, measure traffic, prevent fraud, attribute marketing, improve checkout performance, and understand destination demand. Users may control some cookies through browser settings or consent tools, although disabling certain cookies may reduce website functionality.

8. Retention

Telzen keeps personal data only for as long as reasonably necessary for the purposes described in this Privacy Policy, including contract fulfillment, account administration, warranty handling, chargeback defense, tax and accounting retention, fraud analysis, and legal compliance. Retention periods may vary depending on the type of data, destination country rules, and payment or audit requirements.

9. Security

Telzen uses commercially reasonable technical and organizational measures to protect personal data, including access controls, provider-based security safeguards, payment-tokenization flows where available, environment restrictions, and monitoring against unauthorized access or abuse. No system can be guaranteed to be completely secure, and customers should use strong passwords, secure devices, and trusted networks.

10. Customer rights

Depending on applicable law, users may have rights to access, correct, delete, restrict, object to, or port certain personal data, and to withdraw consent where consent is the legal basis for processing. Telzen may require identity verification before fulfilling a request and may retain information where required by law, payment rules, fraud-prevention needs, or legitimate dispute-defense obligations.

11. Marketing communications

Telzen may send service-related communications necessary to deliver orders, activate products, manage accounts, provide invoices, handle security events, and respond to support requests. Promotional communications may be sent where lawful and may be unsubscribed from using the method provided in the message or by contacting support.

12. Children

Telzen services are not directed to children under the age required by applicable law to form a binding contract for digital services in their jurisdiction. Where a parent or guardian believes a child has submitted personal data unlawfully, Telzen should be contacted so the matter can be reviewed.

13. Third-party links and provider policies

The website or support materials may include links to third-party websites, carrier pages, payment services, app stores, or provider portals. Telzen is not responsible for the privacy practices of third parties, and customers should review the privacy notices of relevant payment processors, provisioning partners, and device or platform vendors separately.

14. Updates to this Privacy Policy

This Privacy Policy may be updated from time to time to reflect changes in law, products, providers, payment methods, fraud controls, or operational practices. The updated version becomes effective when posted on the website unless a later date is stated.

15. Contact

Privacy and legal notices, access requests, correction requests, deletion requests, and compliance communications should be sent through the contact channel listed on the Telzen website. For higher-risk fraud, payment, or legal matters, additional verification may be requested before action is taken.
