Privacy Policy

Last updated: November 12, 2026

This policy explains what information SeedlessPay collects, why we collect it, how long we keep it, and the choices you have. SeedlessPay is used by people in many countries, so we wrote it to be clear for everyone.

Who we are

SeedlessPay is run by Sithu Nyein, an individual based in Myanmar. SeedlessPay is not yet a registered company. If you have any question about your privacy, email us at hello@seedlesspay.com.

What we never collect

We never receive your passkey, your Face ID or fingerprint, or anything that could move your money. Your passkey is created and kept by your device or your password manager (for example iCloud Keychain or Google Password Manager). This website does not use cookies for advertising or analytics, and it does not use tracking tools.

What we collect and why

• Your account. When you create a wallet, we store your passkey's public key, its ID and your wallet address. A public key cannot be used to sign anything. We store it so you can sign in and use the same wallet on any device where your passkey is available.
• Sign-in. When you sign in, we keep a session cookie so you stay signed in for up to 30 days. It is required for the app to work and is deleted when you sign out.
• Invoices. When you create an invoice, we store the amount, what it is for, your wallet address and, if you add them, your name, your client's name and the due date. When an invoice is paid, we also store the payment details from the blockchain: the payer's wallet address, the date and the transaction ID.
• Money you send. When you send USDC from the app, we store the transaction ID, the receiving address, the amount and the date, so you can see your history and download your records.
• Saved addresses. If you save an address, we store it with the name you give it.
• Waitlist. If you join the waitlist, we store your email address and the date you joined, and use it only to invite you to SeedlessPay and send important updates about the beta.
• Emails you send us. If you email us, we receive your email address, your name if you include it, and your message, and use them only to reply to you.
• Abuse protection. To stop spam and attacks, we keep a one-way scrambled version of your IP address for one hour when you use certain features. It cannot be turned back into your IP address.

We use this information only to provide SeedlessPay to you, because you asked us to (for example by creating an invoice or joining the waitlist), and to keep the service secure. We do not sell, rent or share your information for marketing.

Who can see your invoices

Anyone who has an invoice link can see the details on that invoice. Only share the link with the person who should pay it. Your list of invoices, your history and your saved addresses are only visible to you when you are signed in.

Information stored in your browser

The app saves your passkey's ID and public key and your light or dark theme choice in your browser, so it can find your wallet quickly. This information stays on your device and is not used for tracking.

Payments on the blockchain

SeedlessPay payments are recorded on the Avalanche blockchain. Blockchain records are public and permanent, which means anyone can see wallet addresses, amounts and the time of each payment. We cannot change or delete information that is recorded on a blockchain.

Service providers and international transfers

We use a small number of providers to run SeedlessPay. They process information only to provide their service to us:

• Vercel hosts the website and app and processes basic technical information such as your IP address and the pages you request. Vercel Privacy Policy
• Upstash stores account, invoice and waitlist data. Upstash Privacy Policy
• Pimlico submits your wallet's transactions to the blockchain and pays the network fee, and sees your wallet address and the transactions you make.
• ImprovMX and Google (Gmail) receive and store emails sent to us.

These providers may process information in countries other than yours, including the United States. Data protection laws there may be different from the laws where you live.

How long we keep information

• Invoices and their payment details: 2 years from the date the invoice is created, then deleted automatically.
• Your account, history and saved addresses: until you ask us to delete them.
• Sessions: up to 30 days, or until you sign out.
• Waitlist emails: until SeedlessPay launches or you ask us to remove them.
• Scrambled IP addresses: one hour.

Your rights

Wherever you live, you can ask us to tell you what information we hold about you, to give you a copy, to correct it, or to delete it. You can also download your invoice and payment records from the app at any time. Email hello@seedlesspay.com and we will reply within 30 days. Deleting your account does not delete records on the blockchain, and it does not affect the money in your wallet, which you can still reach with your passkey.

If you live in the European Union, the United Kingdom or another place with similar laws, you also have the right to object to how we use your information and to complain to your local data protection authority.

Children

SeedlessPay is not intended for anyone under 18 years old, and we do not knowingly collect information from children.

Changes to this policy

If we change this policy, we will post the new version on this page and update the date at the top. If a change is important, we will also tell you in the app.
