Terms of Service

Last updated: April 9, 2025

Welcome to Back4Sats – a Bitcoin-based cashback platform where users can earn sats (satoshis) for shopping at participating online stores.

By using our services, you agree to the following Terms of Service. If you do not agree with any part of the terms, you should not use the platform.

1. Description of the Service

Back4Sats allows users to earn Bitcoin cashback by visiting affiliated stores through our platform and completing qualifying purchases. Cashback is paid exclusively in Bitcoin, either via:

  • Lightning Network (including BOLT12 offers)
  • On-chain Bitcoin transactions

Users may optionally create an account to manage their earnings and payouts. However, account creation is not mandatory to receive cashback.

Back4Sats does not act as a custodian or wallet provider. At no point does Back4Sats hold or store user funds. Cashback values shown in user accounts represent pending or expected rewards, not available balances.

Payouts are initiated automatically or manually only once a qualifying purchase has been confirmed and commissions received from the merchant.

2. Account Registration

You may access Back4Sats in one of the following ways:

  • With a traditional account (email and password)
  • Through third-party sign-in providers (e.g., Google)
  • Via LNURL-auth compatible Lightning wallets
  • Without creating an account, by providing a BOLT12 offer at the time of activating cashback

You may create and use multiple accounts. It is your responsibility to manage them properly.

3. Cashback Tracking and Payouts

Users with an account can manually request payouts at any time through their dashboard. This applies to both Lightning and on-chain Bitcoin withdrawals.

  • Cashback amounts and their eligibility depend on the merchant's confirmation of a completed purchase.
  • Users providing a BOLT12 offer without creating an account will receive payouts automatically to invoice generated based on the provided BOLT12 once the store confirms the transaction.
  • If a Lightning channel is not open, and the cost to open a channel exceeds the cashback amount, payout may fail.
  • In such cases:
    • The sats will not be lost.
    • The unprocessed payout will be queued and accumulated with future cashback for the same BOLT12 offer.
    • Once the accumulated amount exceeds the required threshold, the payout will be retried.
  • If a payout remains unfulfilled for more than 12 months due to continued inability to deliver, the cashback may expire.

The cashback amount is calculated as follows: once the merchant confirms a successful transaction, we receive a commission from the merchant in a local currency (e.g., EUR). A majority portion of that commission is allocated to the user as cashback — the remaining part is retained as our service fee. The user’s portion is then converted to USD at the current exchange rate, and subsequently to Bitcoin (BTC) based on the prevailing Bitcoin price at the moment the cashback is recorded by the store, which typically occurs 1–2 days after the purchase. This exchange rate is locked in and does not change later, even if the cashback is approved by the merchant at a later date.

User accounts do not include immediate or withdrawable balances. All amounts shown are indicative and pending merchant confirmation. Payouts are only executed upon confirmed eligibility and are subject to transaction thresholds and technical feasibility.

4. Fees and Limitations

  • Any fees associated with Bitcoin or Lightning transactions (e.g., channel opening fees, routing fees) are the responsibility of the user and are deducted from the cashback amount.
  • Back4Sats is not liable for failed payouts caused by wallet-specific limitations or insufficient Lightning Network infrastructure on the user's end.

5. Privacy and Data Usage

We respect user privacy. Personal data is only collected when necessary to operate the service and process payments. Refer to our Privacy Policy for full details.

6. Limitation of Liability

Back4Sats makes reasonable efforts to ensure the platform operates as expected. However, we do not guarantee:

  • That cashback will always be tracked or paid if technical errors occur.
  • That Lightning or on-chain payouts will succeed in all cases.
  • That specific wallet configurations (e.g., Phoenix, Breez) will always support automated payouts.

Users accept all risks related to using non-custodial Bitcoin solutions.

7. Changes to the Terms

These Terms may be updated periodically. Continued use of the service after changes implies acceptance of the updated terms.

9. Legal and Regulatory Disclaimer

Back4Sats is not a bank, financial institution, virtual asset service provider (VASP), or payment processor. The platform does not store, hold, or manage user funds. Cashback rewards are promotional and conditional in nature, granted only after confirmed transactions and receipt of funds from affiliate partners.

In compliance with applicable anti-money laundering (AML) regulations, Back4Sats may require identity verification (KYC) for users whose payouts exceed the equivalent of 1,000 EUR within a 12-month period or when suspicious activity is observed. Back4Sats reserves the right to suspend or delay payouts until necessary verification is completed.

Cashback balances displayed in user dashboards are informational and do not represent actual funds held by the platform.
