Donations

Donations

NOOP is completely free and always will be. Nothing here is a paywall, and every feature works fully without contributing anything. The app never asks you to pay, and you'll never be asked twice.

That said, keeping NOOP independent, anonymous, and offline means it runs on one person's time and personal dollars. If the project is useful to you and you want to help make sure it keeps going — paying for test hardware, reverse-engineering time, and new platform builds (Windows, Android, iOS) — you can chip in. It's 100% optional and entirely your choice.

Why donate?

The honest reality: NOOP is unfunded, and donations directly decide whether the project continues and grows. Contributions go toward:

• A Windows companion app — bringing the same local-first, offline experience to PC.
• Full Android support — complete recovery, strain, and sleep scoring on Android (live HR already works).
• iOS completion — finishing the experimental community build and keeping it current.
• More features and polish — deeper analytics, broader WHOOP firmware support, and refinements to existing screens.
• Test hardware and reverse-engineering time — the cost of keeping up as WHOOP's firmware evolves.

Donations are a thank-you, not a transaction. Your data, access, and the app itself are never gated by payment.

Crypto-only — here's why

Donations are crypto-only, on purpose. Staying anonymous means NOOP has no company, no investor, no real identity attached to it. That anonymity protects both the project (no legal target, no personal liability) and you (no PayPal account, no trace). It's not a hurdle — it's quick, global, and private for both of us.

How to donate (2 minutes, even if you're new to crypto)

You don't need to "be into crypto" to send a few dollars:

1. Install a mainstream exchange app — Coinbase, Binance, Kraken, or Cash App (Cash App lets you buy and send Bitcoin directly without extra apps).
2. Buy a small amount of Bitcoin or Ethereum — even $5–10 genuinely helps. You can usually pay with a debit card or bank transfer.
3. Tap Send / Withdraw, paste the address for your coin below, and confirm. Done.

Important safety notes

• Only ever send a coin to its own network. Send Bitcoin to the Bitcoin address, Ethereum to the Ethereum address, etc. Sending a coin to the wrong network loses the funds — there's no recovery.
• Copy the full address and double-check the first and last few characters before sending. Crypto transactions are irreversible.
• Exchange fees are normal (they go to the network, not to NOOP). Sending one slightly larger amount once is better than many tiny transfers.
• In the app, open Support to see each address with a scan-to-donate QR code — you can point your exchange app's camera at it instead of copy-pasting.

Donation addresses

All four are standard receiving addresses on their respective networks. Pick whichever you already hold — there's no preference. Always copy the full address and verify the first and last characters before sending. Remember: only send a coin to its own network.

Technical notes:

• The ETH address is a standard EVM address, so it also receives on Ethereum-compatible networks (like Polygon or Arbitrum) if your wallet uses them — but when in doubt, send on Ethereum mainnet.
• The XRP Ledger address is self-custodied and requires no destination tag.

Can't or prefer not to donate money?

No problem — there are other ways to help that matter just as much:

• Star this repo — it helps others discover NOOP.
• File a good bug report — including device type, OS version, and steps to reproduce.
• Share a strap log — if something isn't working right, logs help narrow down protocol issues.
• Test on your own hardware — especially WHOOP 5.0/MG pairing and newer features.
• Spread the word — tell other WHOOP users about NOOP.
• Contribute code — pull requests, even small ones, move the project forward. See Contributing.

What donations are not

• Not a subscription. One-off, whenever you like, never recurring.
• Not required for any feature. Everything works fully without paying anything.
• Not a license purchase. NOOP is already free to use, fork, and contribute to under its existing license (PolyForm Noncommercial). See Contributing.
• Not tied to your data or identity. NOOP has no server, no account, and no record of who has or hasn't donated.

The project's promise

NOOP stands on years of community reverse-engineering and exists for one reason: to let you read your own biometric data from your own device, on a machine you control. Keeping it free, keeping it anonymous, and keeping it offline is the whole point. Donations help, but that promise never has a price tag.
