2. Service Provider or Satsback.com or Satsback: Timechain sp. z o.o. with its registered office at al. Powstania Warszawskiego 15, 31-539 Kraków, Poland, registered in the Register of Entrepreneurs of the Polish National Court Register (Krajowy Rejestr Sądowy) maintained by Sąd Rejonowy dla Krakowa-Śródmieścia w Krakowie, XI Commercial Division, under KRS number: 0000800167, NIP: 6793188638, REGON: 384180504, being the provider of the services made available on the Platform, who can be contacted by email at: [email protected];
3. Platform: a web application available on www.satsback.com, owned and maintained by the Service Provider;
4. User (also "you" or "your"): any natural person at least 18 years old who uses the Platform and Services offered through it without any connection to their professional or business activity (consumer). Throughout these Terms and Conditions, "you" and "your" refer to the User;
5. Account: an account run for you by the Service Provider, authenticated through email and password, Nostr login (NIP-07/NIP-46), or LNURL-auth, being a collection of resources in which your data and information about your activities within the Platform is stored;
6. Satsback Reward: a reward expressed in a fraction of a bitcoin (so-called satoshis or sats);
7. Advertiser (also "Merchant"): a third-party e-commerce business affiliated with Satsback and featured on the Platform; Advertisers may be designated as "Standard" (verified tracking reliability) or "Experimental" (newly added with limited tracking history), with different service levels as described in § 6.15;
8. Offer: an opportunity made available to you to receive a Satsback Reward from the Service Provider for purchasing Advertisers' goods or services using the Platform and/or Browser Extension; the Offer does not constitute an offer within the meaning of the Polish civil code.
9. Service: Satsback.com's service that allows you to take advantage of the Offers;
10. Browser Extension: an auxiliary software owned and maintained by the Service Provider add-on that enhances or modifies a web browser's functionality, allowing you to take advantage of the Offers.
The subject of the Terms and Conditions is to determine:
1. Rules of operation of the Platform;
2. Rules of providing Services;
3. Rules of processing of personal data by the Service Provider and the use of cookies within the Platform.
You declare that you acknowledge that the Platform is in beta and that minor errors in its operation are possible.

§ 2. Using the Platform

The Platform is offered to you solely for the delivery of the Service by the Service Provider.
The Service is offered free of charge.
The access to and the use of the Platform within the site are free of charge.
The Service Provider does not sell Merchant's goods or services affiliated on the Platform and you cannot buy them on the Platform.
Prior to the payment of the Satsback Rewards, you will be provided with the information in your Account showing the amount of the Satsback Reward awarded to you. Bitcoin ownership is transferred to you only upon successful payment to your Lightning wallet. At no point does the Service Provider custody digital assets on your behalf.
The use of the Platform is not related to specific risks associated with the use of services provided by electronic means, except for the risks commonly encountered when using the Internet. Irrespective of that, it is recommended to use antivirus software to minimize the risk of infecting your computer with harmful code. If you choose privacy-preserving authentication methods (Nostr, LNURL-auth), you are responsible for securing your own cryptographic keys and maintaining access to your authentication devices or applications.
Truly Free Service: Satsback is free in every sense:
1. No monetary payment required - The Service Provider earns commissions from Merchants, not from you.
2. No "paying with data" - Unlike many similar services, the Service Provider does not collect or sell your personal data for commercial purposes. The Service Provider collects your data only to provide you with the Service.
How This Works:
1. Anonymous signup available: You can create an account using Nostr or LNURL-auth without providing an email address.
2. Minimal data storage: The Service Provider stores only your Satsback Rewards transaction history and click data (to match Merchant transaction reports with your purchases) — both are necessary to provide you with the Service.
3. No browsing surveillance: The Service Provider's browser extension checks if your current site is a Satsback.com Merchant. It does not record, store, or transmit your browsing history.
4. Data flows TO us, not FROM us: Affiliate networks and Merchants send the Service Provider transaction data to calculate your rewards. We do not share your data with them except when you submit a missing transaction claim that requires verification.

Your Data Rights: See § 13 for your full GDPR rights including access, deletion, and portability of your personal data.

§ 3. Rights and Obligations

The Service Provider shall have the right to:
1. temporarily suspend the availability of the Service due to technical reasons, including, without limitation, maintenance, renovation, updating, or upgrading of the Platform;
2. communicate with you, including via e-mail, in connection with the Services;
3. terminate the Service and your Account in the event of a lack of activity within 24 months;
4. suspend the Service and your Account with immediate effect without prior notice in the event of occurrence of the suspected fraud as referred to in paragraph 3 below;
5. block and/or delete duplicate Accounts or all accounts that are associated with you if they are found to be registered by the same person;
6. suspend or terminate your Account if you are found to be using paid advertising or prohibited traffic generation methods in violation of §3 Section 8 item f) and §3 Section 9, without prior notice and with immediate forfeiture of all pending Satsback Rewards;
7. terminate the Service.
Before the termination of the Service and your Account pursuant to § 3 section 1 item c above, you will be notified at least 30 days before deactivation, by email if your Account has an email address, or by Nostr message if you chose Nostr for notifications and we can reach your Nostr inbox, with:
1. Clear warning of pending account closure;
2. Instructions to prevent closure (any login or transaction);
3. Information about requesting payment of any available rewards;
4. Reminder that unclaimed rewards will be forfeited.
An Account with neither, or a suspended Account, may be terminated without this notice.
The suspected fraud, as referred to in Section 1 item d above, includes:
1. Multiple Account Abuse: Creating multiple accounts to exploit referral bonuses or claim offers multiple times, detected through technical analysis;
2. Return Fraud: Systematic pattern of making purchases to earn cashback followed by product returns or payment reversals, as reported by Advertisers or affiliate networks;
3. Affiliate Link Manipulation: Tampering with tracking mechanisms, cookie stuffing, self-referral schemes, or other technical manipulation of the cashback tracking system;
4. Automated/Bot Activity: Use of bots, scripts, or automated tools to create accounts, click offers, or generate fraudulent transactions;
5. Transaction Fraud: Submitting false transaction claims, fake receipts, or claiming rewards for purchases that did not occur or were not properly tracked;

7. Merchant Collusion: Arrangements with Merchant employees or third parties to create fake transactions or fraudulent commissions.
The Service Provider is not a party to any agreement or contract between you and any Advertiser and shall not be liable for any acts or omissions of the Advertiser(s), including without limitation the Advertiser's failure to perform its obligation towards you in connection with:
1. services affiliated on the Platform,
2. delivery of any goods,
3. the statutory warranty or any guarantee for the goods or services delivered.

IMPORTANT: In the cases set out in Section 4 above, you should contact the Advertiser directly. The above does NOT apply to Satsback Rewards. All cashback-related inquiries, missing transaction claims, and reward disputes must be directed ONLY to Satsback.com support ([email protected]), NOT to Advertisers. Advertisers cannot process cashback claims and contacting them about rewards may jeopardize the Service Provider's merchant partnerships.

The Service Provider is not a representative of any Advertiser, which means that they do not act for or on behalf of the Advertiser in any respect when providing the Service, including making any payments of the Satsback Reward to you.
The inclusion of any Advertiser on the Platform does not constitute an endorsement, recommendation, or guarantee of that Advertiser's products, services, reliability, or business practices. You should conduct your own assessment before making purchases.
The Service Provider does not offer any services other than those expressly described in the Terms and Conditions. In particular, the Service Provider does not:
1. hold, manage, provide custody or administration, or otherwise control any bitcoin (or any other cryptoassets) for or on your behalf;
2. provide any service that involves exchanging bitcoin (or any other cryptoassets) for other funds or exchanging funds for bitcoin (or any other cryptoassets);
3. receive, transfer or execute any orders for bitcoin (or any other cryptoassets) on your behalf;
4. provide any services relating to placing bitcoin (or any other cryptoassets);
5. provide any advisory and/or portfolio management services relating to bitcoin (or any other cryptoassets); and/or
6. provide any services that involve transfer of bitcoin (or any other cryptoassets) for or on your behalf.
You are obliged to:
1. use the Platform in accordance with its purpose and the Terms & Conditions;
2. refrain from actions that could negatively affect the Platform or Service Provider's computer systems or make any interference in the Platform;
3. refrain from registering more than one account;
4. refrain from conducting hacking attempts or attacks;
5. refrain from providing and/or uploading any unlawful content to the Platform or to the Service Provider in connection with the Services;
6. refrain from using paid advertising (including but not limited to: paid search ads, display ads, social media ads, influencer sponsorships, affiliate marketing networks, or any form of paid traffic acquisition) to promote your Satsback.com account, referral codes, or drive traffic to the Platform. This prohibition applies whether advertising on Satsback-branded keywords, Merchant brand terms, or generic cashback/rewards keywords. If you are found in violation, your Account will be immediately suspended and all pending Satsback Rewards forfeited.
Prohibited Traffic Generation: You must not use any form of paid advertising or artificial traffic generation to promote your Satsback.com Account or referral codes. This prohibition includes, but is not limited to:
1. Paid search advertising (Google Ads, Bing Ads, etc.) on any keywords;
2. Display advertising networks;
3. Social media advertising (Facebook Ads, Instagram Ads, TikTok Ads, etc.);
4. Influencer marketing or sponsored content where payment is involved;
5. Affiliate marketing networks or partnerships involving financial compensation;
6. Email marketing to purchased or rented email lists;
7. Any automated or bot-driven traffic generation;
8. Pop-up or pop-under advertisements;
9. Incentivized traffic (paying or rewarding users to sign up or make purchases);
10. sharing, distributing and/or publishing tracking links allowing to earn Satsback Rewards on purchases made by a third party, in particular in online communities, forums, social media groups, and/or any public or semi-public places.

Permitted Promotion: Subject to the prohibitions and obligations set out in Section 8 and 9 above, you may share your experiences organically through:

Personal social media accounts (non-paid posts);
Personal blogs or websites (non-paid content);
Word-of-mouth recommendations to friends and family;
Genuine product reviews or testimonials.

Enforcement: Violation of this provision will result in immediate Account suspension and forfeiture of all pending Satsback Rewards, as the Service Provider's agreements with Merchants and affiliate networks strictly prohibit such traffic generation methods.

§ 5. Limitation of the Service Provider's Liability

Although the highest security standards are implemented in securing its servers, Satsback.com is not liable for any temporary and unexpected malfunctions of the Platform caused by cyber-attacks, accidental circumstances, natural disasters, force majeure, or other circumstances beyond the Service Provider's control.
The Platform does not store, send or receive bitcoins or parts thereof. Transfer of the ownership to bitcoin or part of it takes place in a decentralized network and not within the Platform's IT infrastructure.
The Service Provider is not liable for damages or claims arising from and/or relating to:
1. erroneous payments in the event that the error results from:
  1. incorrect payment details provided by you, including an incorrect Lightning address and/or lightning invoice,

The Service Provider shall not be held liable for any services or goods purchased on Advertiser websites, their quality, delivery, guarantee service or warranty, and other claims related to services or goods purchased on the Advertisers' websites via the Platform.

§ 6. The Service

You may take advantage of any number of Offers available via the Platform.
In order to take advantage of the Offer, you need to go to the chosen Advertiser's website using the Satsback.com link and/or browser extension pursuant to § 7 below and make a purchase there, in compliance with the terms, rules and best practices indicated on the Satsback.com website, as well as on the website of the respective Advertiser.
The amount of the Satsback Reward shall be set by the Service Provider as a percentage of the total value of each of your purchases and shall be communicated to you in the process of taking the Offer. The percentage rate may vary depending on the Advertiser's offer(s). The general information of current percentage rate is available on the Platform in the "Stores" tab. Depending on the Offer, the Satsback Reward may be presented as an amount remaining within a certain range, in which case the final amount of the Satsback Reward will be unilaterally determined within that range by the Service Provider.
The basis for calculating the value of the Satsback Reward is the net value of the purchases, excluding shipping costs, taxes, packaging, or additional services such as the extended guarantee.
The Advertiser has the right to exclude products, services, or groups of products or services from the Offer.
The maximum Satsback Reward paid out on a one-off basis may amount to the equivalent of EUR 500.
The maximum amount that you may receive on a one-off basis as the Satsback Reward during a single transaction is the amount of bitcoin equivalent to EUR 500.
The Satsback Reward is paid after the Advertiser approves the transaction and confirms its final amount. The approval period varies depending on the Advertiser and it is not shorter than the period during which you have the right to withdraw from the agreement concluded with the Advertiser. On average this takes 60 days. The estimated period is given only for information purposes and does not bind Satsback.com in any way.
You acknowledge that you are aware of the fact that the Satsback Reward is denominated in bitcoin and that its value in your local currency may change over time depending on bitcoin's market value.
Commission Disclosure:
1. Important Transparency Notice: The Service Provider earns affiliate commissions from the Advertisers when you make purchases using the Platform. The Satsback Reward is an award paid by the Service Provider (and not by the Advertisers) to you calculated based on the affiliate commissions earned by the Service Provider.
2. Effect on Prices: In most cases, using the Services does not affect the price you pay to Advertisers. However, some Merchants may adjust certain promotional offers or discounts (such as loyalty program benefits) when you purchase their goods or services using the Platform. Any such variations are determined solely by the Merchants and are outside the Service Provider's control.
In the event of deleting your Account by the Service Provider, your ability to participate in the Offers ceases on the date of deleting the Account. The Satsback Reward credited to you due to taking the Offer before the deletion of the Account will be paid by the Service Provider within 5 business days following the end of the period referred to in Section 8 above.
In order to use the Service properly and to make it possible for the Service Provider to credit the Satsback Reward, it is necessary to:
1. have an active Account;
2. have ad-blocking software (Adblock or similar) disabled on Merchant websites when making purchases;
3. log in to the Platform and not delete cookies and other website data until the transaction is concluded on the Advertiser's website;
4. select the Advertiser on the Platform and complete the transaction on the Advertiser's website.
To receive the Satsback Reward, it is necessary to have an active Lightning Network wallet with LNURL technology support (e.g., Blink, Phoenix, Wallet of Satoshi) and provide the Service Provider with a valid address of such Lightning Network wallet or a lightning invoice created by your wallet.
Merchant-Specific Restrictions: Certain Advertisers may impose additional restrictions on cashback eligibility, including but not limited to:
1. Exclusion of specific product categories, brands, or SKUs;
2. Limitations on the use of non-Satsback.com coupon codes or promotional offers;
3. Geographic restrictions based on shipping address or billing location;
4. Customer type restrictions (new vs. existing customers);
5. Order value thresholds (minimum or maximum purchase amounts).
Such restrictions will be communicated on the Advertiser's page within the Platform where available. The Service Provider is not responsible if your purchase is ineligible due to merchant-specific restrictions, and affected rewards may be voided.
Advertiser Designation and Service Levels:
1. Standard Advertisers: Merchants with established tracking reliability. For Standard Advertisers:
  1. Missing transactions will be investigated per § 11;
  2. Manual crediting considered for verified tracking failures;
  3. Historical performance data available.

  2. Manual crediting requests evaluated case-by-case with limited guarantee;
  3. You assume greater risk of tracking failures;
  4. Status may be upgraded to Standard Advertisers after successful tracking validation period.
The Service Provider reserves the right to designate Merchant status and change such designation based on tracking performance data.

§ 7. Browser Extension

1. Automatically detecting cashback opportunities at participating Merchants when you visit their stores;
2. Activating Offers with one click;
3. Tracking purchases for Satsback Reward calculation;
4. Notifying you of available Satsback Rewards and special offers.

4. Installation of the Browser Extension on a device constitutes your consent to real-time Merchant detection;
5. You may disable or uninstall the browser extension at any time without affecting earned Satsback Rewards;
6. Using privacy tools or ad-blockers may interfere with tracking your purchases using the Browser Extension which may result in the loss of the Satsback Reward;
The browser extension has the following functionalities:

2. It does NOT change prices you pay to Merchants for goods or services;
You may:
1. Pause the Browser Extension temporarily for specific browsing sessions;
2. Exclude specific websites from Browser Extension functionality;
3. Adjust notification settings and frequency;
4. Remove all extension data from your browser by uninstalling the Browser Extension.

You are prohibited from using referral codes to generate multiple accounts.
Accounts of users who engage in such activities will be blocked from our services.
Satsback.com reserves the right to change the terms of the referral program at any time due to changing market conditions, risk of fraud, or other reasons.

The Service Provider may terminate the Account maintenance agreement if you violate the generally applicable law or the provisions of the Terms and Conditions. Account deletion by the Service Provider may occur after the Service Provider has sent you an email warning about the possibility of deleting your Account within not less than 72 hours.
More Favorable Terms: Because Satsback.com is a genuinely free service (not a "data as counter-performance" arrangement under EU Digital Content Directive), the 14-day withdrawal period for paid digital services does not apply.
However, we provide MORE favorable terms: you may terminate your Account at any time, without reason, with immediate effect (§ 14.1). This exceeds EU minimum requirements for free services.

§ 15. Final Provisions

The Terms and Conditions come into effect on November 27th, 2026. The previous version dated 13.02.2026 is superseded.
In the event that any of the provisions of the Terms and Conditions prove to be invalid, ineffective, illegal, or unenforceable in whole or in part, this circumstance will not affect the validity of the remaining provisions of the Terms and Conditions.
To matters not covered by the Terms and Conditions, the provisions of Polish law shall apply. In the case of consumers, the choice of law does not deprive you of the protection granted under the provisions that cannot be excluded by an agreement under the country's law in which you have your residence.
The Service Provider reserves the right to make changes in the Terms and Conditions after informing you via the Platform's website.
Before the amendments to the Terms and Conditions enter into effect, you may object to the proposed changes and terminate the service agreement.
The Terms and Conditions content is available to you free of charge; you may save its content on your device or print it. The Service Provider informs that using the Platform through a web browser, including the Satsback.com Service, may involve the cost of connection to the Internet (data transfer fee) per the tariff package of your service provider.

§ 16. Service Conformity and Updates

Service Quality Commitment: We commit to:
1. Maintain core functionality as described in these Terms and Conditions;
2. Ensure compatibility of the Platform with current browser versions;
3. Provide security updates promptly;
4. Fix significant bugs within reasonable timeframes.
Your Remedies for Non-Conformity:
1. If the Service does not conform to what was promised, you may request Service restoration to conformity.
2. In addition, you may receive a proportionate reduction (if applicable) or terminate the agreement if issues persist after reasonable attempts to fix, if:
  - Bringing the Service into conformity with the agreement is impossible or requires excessive costs;
  - The Service Provider did not bring the Service into conformity with the agreement;
  - The non-conformity of the Service with the agreement persists even though the Service Provider has tried to bring the Service into conformity with the agreement;
  - The non-conformity of the Service with the agreement is significant enough to justify a price reduction or withdrawal from the agreement without prior use of the protection measure;
  - It is clear from the Service Provider's declaration or circumstances that they will not bring the Service into conformity with the agreement within a reasonable time or without undue inconvenience to you.
Service Updates:
1. Security updates: Will be applied immediately for critical issues, with 15 days notice for non-critical;
2. Feature updates: 30 days advance notice;
3. Your rights: You may refuse non-essential updates that don't affect security.
