Support Flowvault

Donate in 100+ cryptocurrencies. No sign-up, no email required from donors.

Flowvault doesn't run ads, sell data, or ask for your email. That means the usual ways an app pays for itself aren't available to us — which is the whole point. Donations cover Firebase hosting, domain & TLS, the drand beacon monitoring we use for time-locked notes, and continued development.

We use NOWPayments as the crypto processor. Their donation widget accepts ~100+ coins, generates a fresh deposit address per donation (so later donors can't correlate addresses across contributions), and does not require donors to create an account or provide an email. If you want the most private option, send Monero (XMR) — it hides amounts, senders, and receivers at the protocol level.

Donate

Pick a coin and an amount. The widget gives you a one-time deposit address — your browser sends funds directly to the blockchain from there.

Widget not loading? Some ad-blockers filter nowpayments.io.

Prefer a full-page flow?

Open the donation page in a new tab — same widget, more room to read it:

Backup link

If the vanity link ever goes down, this one goes directly to our donation endpoint:

Privacy notes

Donors don't need an account.The NOWPayments donation widget lets anyone contribute without signing up. Receipts are optional — only required if the donor wants one for themselves.
Fresh addresses per donation. The widget generates a one-time deposit address for each session, so two donors looking at the same page see different addresses and can't cross-reference each other on-chain.
We see no donor metadata.On our side we receive the forwarded funds and aggregate totals — not an IP, email, or identity. You're free to donate through Tor or a VPN; NOWPayments supports both.
Choose Monero for maximum privacy. Bitcoin, Ethereum, Litecoin, USDT, and Solana are pseudonymous: anyone who later learns a donation address can trace its history. Monero hides amounts, senders, and receivers cryptographically.

Can't or don't want to donate?

Honestly, no pressure. Using Flowvault, telling a friend who needs it, starring the repo, filing a thoughtful issue, or sending a PR all help the project real-world as much as a few dollars does. We mean that.

And thank you, either way. Back to the app.
