Terms of use

Effective: November 15, 2026 · Operator: Millennial R&D, LLC ("we", "us")

PLEASE READ SECTIONS 12 TO 16 CAREFULLY. THEY CONTAIN A BINDING ARBITRATION AGREEMENT, A CLASS-ACTION WAIVER AND LIMITATIONS OF LIABILITY THAT AFFECT YOUR LEGAL RIGHTS.

By installing or using the Spaceback desktop app ("the app") or the Spaceback website ("the website"), together "the Service", you agree to these terms. If you do not agree, do not use the Service.

  1. Eligibility. You must be at least 18 years old (or the age of majority where you live) and able to form a binding contract. If you use the Service for an organisation, you confirm you may bind it, and "you" includes it.
  2. What the Service does. It helps you find email you may want to remove and moves it to your provider's Trash, archives mail to your computer, and finds duplicate WhatsApp downloads on your computer. You decide what is moved. The app does not permanently delete mail, but your provider may empty Trash automatically after a period (for example Gmail after 30 days), after which mail may be unrecoverable. Moving local files goes to your computer's Trash or Recycle Bin, whose behaviour we do not control.
  3. Your responsibility. You are solely responsible for what you select, confirm and move. Review every selection. Keep your own backups of anything you cannot afford to lose. Use the protect feature for messages that must never be moved. You must have the right to access every account and folder you connect, and you must comply with the law and with your provider's terms. The app starts in scan-only mode; by switching on "Allow moving to Trash" you accept the risk described here.
  4. Third-party services. The Service works through Google, Microsoft, mail servers, Stripe and other third parties. Their terms and policies apply to your use of them. We do not control them, do not endorse them and are not responsible for their availability, changes, outages, limits, fees, errors or data handling. They may change or withdraw access at any time.
  5. Privacy. See the privacy policy.
  6. Licence. Proprietary software of Millennial R&D, LLC | WMB, all rights reserved. Subject to these terms we grant you a limited, revocable, non-exclusive, non-transferable licence to use the app for your own personal or internal business purposes. You may not copy, modify, sell, sublicense, reverse engineer (except where the law forbids this restriction), remove notices from, or circumvent any licence check or technical limit of the Service. Third-party components keep their own licences (see the SBOM). We keep all rights not expressly granted.
  7. Acceptable use. Do not use the Service unlawfully, to access accounts you are not authorised to use, to interfere with or overload the Service or any provider, to attempt to bypass billing or entitlements, or to infringe anyone's rights. We may suspend or end access for breach of these terms or to protect the Service, users or third parties.
  8. Feedback. If you send us suggestions, you grant us a perpetual, worldwide, royalty-free licence to use them without obligation to you.
  9. Website, plans and payments. The website offers a demo mailbox, a WhatsApp cleaner that runs in your browser, and paid plans (a one-time Cleanup Pass and subscriptions) that unlock moving mail to Trash. Payments are processed by Stripe; you authorise us and Stripe to charge your chosen payment method. Subscriptions renew automatically at the then-current price until you cancel in Billing; cancellation takes effect at the end of the paid period and you keep access until then. Prices may change on notice before your next renewal. Fees are exclusive of taxes, which you pay where applicable. Discount codes have no cash value and may be withdrawn.
  10. Refunds. Refunds are discretionary and decided case by case. To request one, email support within 14 days of the charge, giving your account email and a description of the problem. After verification, we may grant a full or partial refund, or a credit, only if you were materially inconvenienced: that is, you could not use the paid features you were charged for because of an error, outage or decision on our part, and we did not resolve it within a reasonable time. We do not refund for change of mind, unused time, Cleanup Passes already used, problems caused by your provider, your devices or your own selections, or accounts suspended or terminated for breach of the terms. Except where the law gives you a non-waivable right, fees are otherwise non-refundable and we are not obliged to refund partial periods or unused passes. Any refund decision is made by us in good faith and is not an admission of liability.
  11. Changes and termination. We may change the Service, its features, pricing and these terms at any time. For material changes to these terms we will post the new version and update the effective date; continued use after that means you accept them. You may stop using the Service and delete its data at any time (Privacy & data, then Delete all local data; on the website, Billing, then Delete my account). We may suspend or terminate your access at any time. Sections that by their nature should survive (including 12 to 20) survive termination.
  12. Disclaimer of warranties. THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE". TO THE FULLEST EXTENT PERMITTED BY LAW, WE DISCLAIM ALL WARRANTIES, EXPRESS, IMPLIED OR STATUTORY, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, NON-INFRINGEMENT, ACCURACY, AND UNINTERRUPTED OR ERROR-FREE OPERATION. WE DO NOT WARRANT THAT SIZE FIGURES, SEARCH RESULTS, DUPLICATE DETECTION OR UNDO WILL BE COMPLETE OR CORRECT, OR THAT ANY ITEM CAN BE RECOVERED.
  13. Limitation of liability. TO THE FULLEST EXTENT PERMITTED BY LAW: (a) WE AND OUR OWNERS, MEMBERS, MANAGERS, EMPLOYEES, CONTRACTORS, AFFILIATES, LICENSORS AND SUPPLIERS ARE NOT LIABLE FOR ANY LOST, MOVED, DELETED OR UNRECOVERABLE MAIL OR FILES, LOST DATA, LOST PROFITS, LOSS OF GOODWILL, BUSINESS INTERRUPTION, OR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY OR PUNITIVE DAMAGES, HOWEVER CAUSED AND UNDER ANY THEORY, EVEN IF ADVISED OF THEIR POSSIBILITY; AND (b) OUR TOTAL AGGREGATE LIABILITY FOR ALL CLAIMS RELATING TO THE SERVICE IS LIMITED TO THE GREATER OF THE AMOUNT YOU PAID US IN THE 12 MONTHS BEFORE THE CLAIM AROSE AND US$50. These limits apply even if a remedy fails of its essential purpose. Some places do not allow certain limits, so some of this may not apply to you; in that case our liability is limited to the minimum the law allows. Nothing in these terms limits liability that cannot be limited by law.
  14. Indemnity. You will defend, indemnify and hold harmless us and our owners, members, managers, employees, contractors and affiliates from any claim, loss, liability, damage and expense (including reasonable attorneys' fees) arising from your use of the Service, your content or accounts, your breach of these terms or the law, or your violation of any third party's rights, including a provider's terms or another person's mail.
  15. Binding arbitration of all disputes. Please read this section carefully. (a) Scope. Except as stated in (e), any dispute, claim or controversy between you and us arising out of or relating to these terms, the Service, the privacy policy, billing, or any earlier or later agreement between us, including its existence, scope, validity, enforceability and arbitrability, will be resolved exclusively by final and binding arbitration and not in court. This applies to claims of any kind: contract, tort, statute, fraud, misrepresentation or otherwise. (b) Rules and place. The arbitration will be administered by the American Arbitration Association ("AAA") under its Consumer Arbitration Rules (or, if you are not a consumer, its Commercial Arbitration Rules) in force when the claim is filed, before a single arbitrator. The seat is the State of Georgia, United States, and hearings will be held there or, at your choice for consumers, by video or telephone or in your home county. The Federal Arbitration Act governs this section. The arbitrator applies the law stated in section 18 and may award only individual relief that the law and these terms allow, and must follow the limits in sections 12 and 13. Judgment on the award may be entered in any court with jurisdiction. (c) Fees. AAA fees are allocated under its rules. We will pay any filing, administrative and arbitrator fees that the AAA consumer rules require us to pay, and we will not seek attorneys' fees from you unless the arbitrator finds your claim frivolous or brought in bad faith. (d) Informal resolution first. Before filing, the claimant must send the other party a written notice describing the dispute and requested relief (to the contact address below, or to the email on your account) and allow 60 days to try to resolve it in good faith. Time spent on this step pauses any limitation period. (e) Exceptions. Either party may bring an individual claim in small-claims court if it qualifies and stays there, and either party may seek urgent injunctive relief from a court to protect its intellectual property or confidential information, pending arbitration. (f) Confidentiality. To the extent permitted by law, the arbitration and its result are confidential, except as needed to enforce an award or comply with law. (g) Opt out. You may opt out of this section 15 and section 16 by emailing support+spaceback@millennials.tech within 30 days of first accepting these terms, with the subject "Arbitration opt-out", your name and the account email. If you opt out, disputes go to the courts in section 18, and the remainder of these terms still applies. (h) Changes. If we change this section 15 (other than an address), you may reject the change by notice within 30 days of it being posted and the earlier version will apply to disputes that arose before the change.
  16. Class-action and jury waiver. TO THE FULLEST EXTENT PERMITTED BY LAW, YOU AND WE EACH WAIVE THE RIGHT TO A JURY TRIAL AND THE RIGHT TO BRING OR TAKE PART IN A CLASS, COLLECTIVE, CONSOLIDATED, REPRESENTATIVE OR MASS ACTION. Claims may be brought and arbitrated only individually, and the arbitrator may not combine claims or preside over any class or representative proceeding. If this section is found unenforceable as to a claim, that claim (and only that claim) will be heard in the courts in section 18, after any arbitrable claims are decided, and the class waiver remains effective for all other claims.
  17. Time limit. To the extent the law allows, any claim must be started within one (1) year after it arose, or it is permanently barred.
  18. Governing law and courts. These terms are governed by the laws of the State of Georgia, United States. Conflict-of-laws rules do not apply, and section 15 is governed by the Federal Arbitration Act. For any dispute that is not arbitrated, you and we submit to the exclusive jurisdiction of the state and federal courts sitting in that same place and waive objections to that venue. The UN Convention on Contracts for the International Sale of Goods does not apply.
  19. Export, government and other rules. You will follow applicable export, sanctions and consumer laws. The app is "commercial computer software". If you are in a place where the law gives you mandatory consumer rights that these terms cannot override, those rights are not affected.
  20. General. These terms and the documents they link are the entire agreement about the Service. If a provision is unenforceable it is limited to the minimum extent needed and the rest stays in force (but see section 16 for the class waiver). Our failure to enforce a right is not a waiver. You may not assign these terms without our consent; we may assign them in a merger, sale or reorganisation. We are not liable for delay or failure caused by events beyond our reasonable control. Notices to you may be sent to your account email or posted in the Service. Headings are for convenience only.
