Privacy Policy

The data controller is TudaSim Limited, 42C, 69 Hollywood Road, Central, Hong Kong. We operate the Tuda eSIM service. For any privacy question, write to [email protected].

• Contact details: email address and, optionally, your name.
• Payment confirmation: amount, currency, date and payment status. Cards are processed by our payment provider — we never see or store full card numbers.
• Order and eSIM identifiers: order number, ICCID and the plan you bought.
• Device and installation status: whether the eSIM was installed and activated, and basic technical information needed to deliver it.
• Data usage per plan: how much data was used and remains, so we can show your balance and offer top-ups.
• Partner referral: if a partner referred you (for example, a car rental company), the referral code and your booking reference with that partner.
• Support messages: what you write to us by email or Telegram and our replies.
• Basic analytics and cookies: pages visited and similar technical data (see section 9).

We don’t collect the content of your internet traffic or browsing history.

• To deliver the eSIM and provide connectivity (performance of our contract with you).
• To process payments and refunds.
• To provide customer support.
• To prevent fraud and abuse and keep the service secure (our legitimate interests).
• To comply with legal obligations, such as accounting and tax rules.
• To improve the service, using aggregated or de-identified data where possible.
• To send marketing emails — only with your consent. You can unsubscribe at any time.

We don’t sell your personal data. We share it only as needed:

• Mobile network partners — to provision your eSIM and provide connectivity.
• Our payment processor — to take payments and issue refunds.
• The partner who referred you — only referral and order status (for example, that a plan was bought and activated), never your payment data.
• Service providers who work for us, such as hosting and email delivery, under contracts that protect your data.
• Authorities, when we are legally required to do so.

We and our partners operate in different countries, so your data may be processed outside the country where you live. When we transfer data, we use appropriate safeguards, such as contractual clauses, as required by applicable law.

We keep order and payment records for as long as the law requires (for example, for accounting and tax purposes). Other personal data is deleted after 24 months of inactivity on your account, or earlier if you ask us to delete it and we have no legal reason to keep it.

Depending on where you live, you can:

• access the personal data we hold about you;
• ask us to correct inaccurate data;
• ask us to delete your data;
• object to processing based on our legitimate interests;
• withdraw your consent, for example to marketing emails, at any time.

To use any of these rights, write to [email protected]. We respond within 30 days. You may also have the right to complain to a data protection authority.

We use technical and organisational measures to protect your data, including encryption in transit and restricted access. No system is perfectly secure, but we work to keep risks low.

Our website uses only the cookies it needs to work (for example, to remember your language) and basic, privacy-friendly analytics. We don’t use third-party advertising trackers. If we ever add non-essential cookies, we will ask for your consent first.

The service is not intended for people under 16. We don’t knowingly collect data from children. If you believe a child has given us personal data, write to [email protected] and we will delete it.

We may update this policy. We will publish the new version on this page with a new date, and tell you by email about important changes.
