Security & privacy
Your data is there to run the app — not to sell.
Esender makes money from products, not attention. Here's what that means for your data, how we help keep your account safe, and how to reach us about privacy or security.
Our privacy commitments
Four promises that apply to every Esender app.
They follow from how we make money. When your data isn't the product, there's no reason to collect more of it than we need.
No ads, no feed
We don't place ads in your conversations or build an algorithmic feed around what you do.
We don't sell your data
We don't sell your personal data to advertisers, data brokers or anyone else.
Only what's needed
We aim to collect only the information we need to run each service, support you and meet our legal obligations.
You set the controls
Decide who can reach you, what you share and which notifications you get — in settings you can actually find.
Protecting your account
Practical protections, and a few habits that help.
Security is shared work. Here's what we do, and what you can do, to keep your Esender account and purchases safe.
- Secure checkout. Esender eSIM payments are handled by established payment providers, including card payments and Apple Pay.
- Updates through official stores. We ship fixes and improvements through the App Store and Google Play — keep automatic updates on.
- Official sources only. Install Esender from the App Store, Google Play or links on esender.com, esim.esender.com and this site.
- Lock your phone. A screen lock and your device's built-in security protect every app on it, including Esender.
Data, product by product
What each app needs to work.
A plain-language overview. Our privacy policy has the full detail and takes precedence over this summary.
Esender Chat Live
Your account details and the information needed to deliver messages, calls and media to the people you choose, plus the settings you pick.
Esender eSIM Live
Your email and payment details so we can deliver your plan, plus plan and usage information so you can see your data and get support.
Noteyy Live
No account. Your note is encrypted at rest with AES-256-GCM, then permanently deleted once it's read or expires. Optional passwords are hashed, and note links are kept out of search engines.
Esender VPN Soon
In development. We'll explain what the VPN needs to work, and how that data is handled, before it launches.
Esender Wallet Soon
In development. Payments carry their own requirements, and we'll publish what Wallet needs, and why, before launch.
Your rights & controls
Ask what we hold. Correct it. Delete it.
Depending on where you live, you may have legal rights over your personal data. Wherever you are, you can send us a request.
Access
Ask for a copy of the personal data associated with your Esender account.
Correction
Ask us to fix information that's wrong or out of date.
Deletion
Ask us to delete your account and personal data, except where we must keep records by law.
Staying safe
Esender will never ask for your password or verification codes.
Scammers impersonate companies to take over accounts. If a message, call or email asks for a code or password — even if it looks like it's from us — it isn't.
- Never share a verification code sent to your phone or email
- Be wary of urgent messages about "problems" with your account or eSIM
- Buy eSIM plans only in the Esender eSIM app or at esim.esender.com
- If a friend asks for money in chat, check with them another way first
- Not sure? Ask our support team
Responsible disclosure
Found a vulnerability? Tell us.
We welcome reports from security researchers and anyone else who spots a problem in Esender apps, websites or services. Send it through our contact form with the topic Security report.
We aim to acknowledge your report, keep you updated while we investigate, and let you know when it's fixed. Please give us reasonable time to fix the issue before you disclose it publicly.

- The app, website or service affected, and its version
- Clear steps to reproduce the issue
- What an attacker could do with it
- Screenshots, logs or a proof of concept, if you have them
- How we can reach you for follow-up questions
Please don't
- Access, change or delete other people's data
- Degrade our services, for example with denial-of-service testing
- Use social engineering, phishing or physical attacks against our people
Questions
Security & privacy FAQ
Does Esender show ads or sell my data?
No. There are no ads in Esender Chat and we don't sell your personal data. We make money from products people choose to pay for, like Esender eSIM plans.
What data does Esender eSIM need?
Your email address and payment details so we can deliver your plan, plus plan and usage information so you can track your data and get support. See the privacy policy for detail.
How do I change who can contact me in Esender Chat?
Open the privacy settings in Esender Chat to choose who can message you and what others can see. Visit the help centre if you can't find a setting.
How do I delete my account or request my data?
Contact us from the email address linked to your account and tell us what you'd like to access, correct or delete.
Someone asked me for a code and said they were Esender. What should I do?
Don't share it. Esender will never ask for your password or verification codes. Tell our support team so we can look into it.
Do you pay bug bounties?
We haven't announced a bug bounty programme, so please don't expect a reward. We're grateful for every responsible report and will work with you on a fix — see responsible disclosure.
