Terms of Use & Privacy

Last updated 23 September 2026

XPR Tax (tax.protonnz.com, the “Service”) is operated by Proton NZ (“we”, “us”). It reconstructs a public XPR Network account’s on-chain history and produces data files to help prepare a tax return. By using the Service or paying for an export you agree to these terms. If you don’t agree, don’t use the Service.

1. What the Service is — and isn’t

The Service is a data-preparation tool. It reads publicly available blockchain data, classifies and values transactions, and exports them in formats such as CoinTracking-ready CSV, plus a reconciliation report and point-in-time balance snapshots.

The Service is not tax advice, accounting advice, or financial advice, and we are not your accountant or tax agent. Tax treatment depends on your circumstances and your jurisdiction’s law.

You must independently review and verify every figure before you rely on it or file it, and you are solely responsible for the accuracy and completeness of anything you submit to a tax authority. The output is a starting point for you and your adviser — not a finished return. We strongly recommend a qualified tax professional review it before you rely on it.

2. Accuracy & “best-effort”

We take completeness seriously — the Service cross-checks multiple history nodes, repairs known gaps, and reconciles ledger totals to on-chain balances. However, blockchain history sources can be incomplete or inconsistent, and prices are sourced from third parties.

Classifying on-chain activity involves judgement and may be incomplete or incorrect, particularly for newer or less common protocols, tokens, and complex DeFi activity (for example liquidity provision, lending, staking, farming, cross-chain bridging, or airdrops). Not every application on XPR Network receives dedicated handling; activity we do not specifically model is still captured as generic transfers, which may need reclassification by you or your adviser. Token prices, historical valuations, and currency conversions are estimates from third-party sources and may differ from the values that apply to you.

Accordingly, the output is provided on a best-effort basis and without warranty of any kind as to accuracy, completeness, or fitness for a particular purpose. You must check the data against your own records before using it.

3. Payment, access & refunds

Access is unlocked either by an on-chain payment to the protonnz account with the memo shown at checkout, or by card through Stripe’s hosted checkout. Prices are stated on the site and are the same either way (currently USD 10 per account per year, USD 5 for accounts that stake at least 1,000,000 XPR and vote for protonnz, and up to 5 accounts for USD 20). A payment entitles you to regenerate that account’s export for 12 months from payment.

Card payments are processed by Stripe. We never see or store your card number. If a card payment is refunded or charged back, access for the accounts it covered is revoked.

On-chain payments are irreversible, and because the deliverable is digital and generated on demand, payments made either way are generally non-refundable. If the Service fails to generate your export, or you were charged in error, contact us and we’ll make it right — including re-runs at no charge or, at our discretion, a refund to your wallet or card.

4. Public data & account lookups

All XPR Network transaction data is public on the blockchain. The Service can compile an export for any account whose name is entered and for which a valid payment has been made; it does not verify that the payer controls that account. Do not use the Service to compile data for others in a way that breaches their privacy or any law. Exports contain only information already public on-chain.

5. Privacy & data handling

• No accounts, no sign-up. We don’t ask for names or passwords. On-chain payments are verified by scanning public blockchain data. If you pay by card, Stripe collects your email address and card details as payment processor, under its own privacy policy; we keep a record of the payment (the account names it covers, the amount, and Stripe’s reference) to grant and, if needed, revoke access.
• Request logs: when you start an export we log the IP address and browser user-agent of the request, for security and abuse prevention, and keep them for up to 90 days. We may look up the approximate country and network of that IP address using a third-party IP-geolocation service. Operational alerts (such as the account name exported and its approximate location) are sent to the operator via Telegram.
• What we process: the XPR account name(s) you enter and the public blockchain data associated with them. If you connect a wallet, your public account name is used to look up what you’ve paid for; we never receive your private keys.
• Generated files (CSV, reconciliation, snapshots) are stored only long enough to deliver them — download links expire after 7 days and the files are then deleted. A cached copy of the classified transaction list may be kept for up to 30 days to speed up regeneration. Regenerate any time within your year.
• Third parties: the Service reads from public XPR Network history nodes and price sources (e.g. the protonnz indexer, CoinGecko, ECB via Frankfurter) and is hosted on Vercel and Railway. Card payments are processed by Stripe; IP addresses may be looked up with an IP-geolocation service; operator alerts are delivered via Telegram. Standard server logs may be kept for security and reliability.
• We don’t sell your data. We don’t set advertising cookies.

6. Limitation of liability

To the maximum extent permitted by law, the Service is provided “as is” and “as available”. We are not liable for any indirect or consequential loss, or for any tax, penalty, interest, audit cost, professional fee, missed deadline, or filing error arising from your use of, or reliance on, the output — including any error, omission, or misclassification in it. You rely on the output at your own risk. Where liability cannot be excluded, our total liability to you is limited to the amount you paid us for the export in question. Nothing in these terms limits rights you have under the New Zealand Consumer Guarantees Act or Fair Trading Act that cannot lawfully be excluded.

Indemnity. To the extent permitted by law, you agree to indemnify and hold harmless Proton NZ and its operators from any claims, penalties, interest, losses, or costs arising from your use of the Service, your reliance on the output, or anything you file with a tax authority based on it.

7. Acceptable use

Don’t attempt to disrupt, overload, reverse-engineer, or gain unauthorised access to the Service, and don’t use it for any unlawful purpose. We may rate-limit, suspend, or decline service to protect the system.

8. Changes & governing law

We may update these terms; the “last updated” date reflects the current version. These terms are governed by the laws of New Zealand, and the New Zealand courts have jurisdiction.

9. Contact

Questions, corrections, or a payment that didn’t verify: @protonnz on X.
