Privacy Policy

1. The short version

This policy covers the Nammu iOS app and the nammu.finance website. It explains what we collect, why, who helps us run the service, and how to get your data removed. If anything is unclear, email us. A human will reply.

2. Who we are

Nammu is built and operated by Damgar s.r.o., a company based in Prague, Czech Republic. Our servers run in the United States, and the app is offered in the United States. When this policy says "we," it means Damgar s.r.o. operating as Nammu.

3. What we collect in the app

Your account

You sign in with your email address or with Sign in with Apple. Our sign-in and wallet provider handles the sign-in and creates your self-custody wallet. We store your email address and a link to your wallet.

Your profile

During onboarding you can tell us your first name, a goal you're working toward, how much you plan to add and how often, the causes you care about, how much of your earnings you want to give, and your date of birth. We use your date of birth for one thing: confirming you are 18 or older. None of this is identity verification, and we never ask for a government ID. If you make a pledge in the app, you can attach an optional note to your future self, and we store it with the pledge.

Your wallet and its activity

We keep a record of your wallet address, your balance, your earnings, your transactions and your giving history. We need this to show you your money, keep our books straight, and give your chosen share of earnings to conservation.

Adding money and cashing out

Card payments and bank transfers happen in Coinbase's own flow, under Coinbase's privacy policy. Your card number and bank login go to Coinbase, never to us. We share only what Coinbase needs to start the purchase or cash-out, such as your wallet address, the amount and your country. Afterward Coinbase tells us the amount, the fees, and whether it went through.

App usage and diagnostics

We collect basic usage data, like which screens you open and which features you use, so we can see what works and fix what doesn't. It is linked to your account, never includes the amounts you move, and is never used for advertising. If the app crashes or something fails, it sends us a technical report, such as the app version, device model and what went wrong. We also keep standard server logs to run and debug the service, with secrets scrubbed before anything is written down.

Feedback and support

When you send feedback in the app or contact support, we receive your message, your email address, and your app version and device model, so we can help you.

4. What we deliberately don't do

• No advertising, and no tracking you across other companies' apps or websites.
• No selling or renting your data. To anyone. Ever.
• No access to your location, contacts, photos, camera, or microphone. The app never asks.
• No storing card numbers or bank credentials. Coinbase handles payment details on their side.
• No government ID collection. If Coinbase runs an identity check for a purchase, that happens with Coinbase directly.

5. Your money lives on a public ledger

Your digital dollars (USDC) sit on public blockchain networks. Transactions to and from your wallet address are visible to anyone, by design. That's what makes your balance checkable by you instead of taking our word for it. The ledger shows wallet addresses and amounts. It does not show your name or email, and we don't publish anything that links the two.

6. What we collect on the website

• Waitlist signup: your email, name, country, device type, browser, how you found us, and, if you share it, the rough amount you plan to start with. We send you one welcome email.
• Support requests: your email, your name if you give it, and your message.
• Analytics: page views, and how visitors move through the site, including session recordings. Some of this uses cookies.
• Country lookup: we use your IP address to look up your country.

You can block cookies in your browser. The website still works without them.

8. Who helps us run Nammu

We use trusted service providers to run Nammu. Each gets only what it needs to do its job, and may use it only to provide its service to us:

• sign-in and wallet infrastructure;
• Coinbase, for adding money and cashing out, under its own privacy policy;
• blockchain network providers, which see wallet addresses that are already public;
• cloud hosting, databases and website security;
• crash reporting and product analytics;
• email delivery and internal team tools for alerts and support;
• Apple, to deliver push notifications.

We share data with authorities only if the law requires it. We don't share your information with data brokers or advertisers.

9. Push notifications

Notifications are optional, and you choose whether to allow them. If you turn them on, we store your device's push token so Apple can deliver them. A notification can name a milestone you reached, which for money milestones can include the threshold you crossed, like your first $100. If you'd rather keep amounts off your lock screen, leave notifications off.

10. How long we keep things, and how to delete your account

We keep your information while your account is active. You can delete your account any time in the app, under Profile. When you do, we delete your email, your profile and your sign-in identity, and the app wipes its local data from your device.

A few honest caveats. We keep transaction records for as long as accounting and legal rules require, because money moved and the books have to stay true, and some of those records include a sealed copy of your onboarding answers and any pledge note. The public ledger is permanent, and nobody, including us, can erase past transactions from it. Before deleting your account, you'll need to cash out your balance. The app walks you through it.

11. Your choices

• Ask us what we have about you.
• Ask us to correct it.
• Delete your account in the app, or email us and we'll do it with you.
• Want off the waitlist? Email us and we'll remove you.

Email [email protected] for any of these. We'd rather answer a hundred questions than have one person feel unsure.

12. Age

Nammu is for adults, 18 and up. We check your date of birth at signup, and we don't knowingly collect information from anyone under 18. If you think a minor has an account, tell us and we'll remove it.

13. Where your data is processed

Our servers and database are in the United States, and the app is offered in the United States. If you visit the website from somewhere else, your data will be processed in the United States.

14. Changes to this policy

When we change this policy, we update the date at the top. If a change is significant, we'll tell you in the app or by email before it takes effect.
