Terms of service

Last updated 14 September 2026 · Private beta

These terms are an agreement between you and Pudding App Inc (“Echos”, “we”, “us”), a company in San Francisco, California, for the Echos service at echos.fyi and its API. By creating an account, or by connecting an assistant, script or key to one, you agree to them. If you are agreeing on behalf of a company, you confirm you may bind it. Questions: hello@echos.fyi.

Please read section 12. It contains an agreement to arbitrate disputes individually and a waiver of class actions, with a 30-day opt-out.

1. The service

Echos gives you a receive-only email address (your main address, plus aliases you create) and lets AI assistants, scripts and tools you authorise read the mail that arrives there through a dashboard, an API and an MCP server. Echos does not send email, and nothing done through it can cause email to be sent. Features, limits and prices are as described on the dashboard and in section 5.

2. Eligibility and your account

You must be at least 18 and able to enter a contract. You must give a working contact email and keep it current; it is the only way we or our login provider can reach you. You are responsible for everything done under your account, including by the assistants, scripts and keys you connect, and for keeping your login, keys and OAuth grants confidential. Revoke anything you no longer trust; tell us promptly at hello@echos.fyi if you believe your account has been used without your permission.

3. Acceptable use

You agree not to, and not to let anyone acting for you:

We may suspend or close an account that breaches this section, remove material, and cooperate with lawful requests from authorities. We will tell you what happened unless the law prevents it.

4. Assistants act on your authority

Anything an assistant, script or key does under a grant you approved is done on your instruction. We record every call so you can see it, we let you narrow, pause or revoke any grant at any time, and we mark every piece of mail we hand to an assistant as untrusted third-party text. What an assistant then does — and the terms of the assistant’s own provider — are between you and that provider. We are not a party to those terms and are not responsible for an assistant’s actions or output.

5. Plans, limits, payment

Free includes 5,000 messages a month, 90 days of retention and 5 GB of storage. Pro ($12 a month, or $10 a month billed annually) includes 50,000 messages, one year and 100 GB. Dev ($49 a month, or $39 a month billed annually) includes 500,000 messages, three years and 1 TB. Per-connection and per-account rate limits apply and are shown on the dashboard.

When a monthly message limit is reached, further mail is asked to try again later; sending servers generally retry for up to about 72 hours, so an upgrade within that window loses nothing, but we do not guarantee what any sending server does. Paid plans are billed by Stripe in advance, renew automatically at the then-current price until cancelled, and can be cancelled any time from Billing; a cancelled plan runs to the end of its paid period and is not refunded except where the law requires. Downgrading shortens retention: mail older than the new plan allows is deleted 14 days after the downgrade, with a warning on the dashboard and the chance to export first. Prices and plan contents may change with at least 30 days’ notice on the dashboard; the change applies from your next renewal. Taxes are added where they apply. Free plans may be limited, changed or withdrawn at any time.

6. Your mail and data

Mail sent to your addresses and everything derived from it is yours. You grant us only the licence we need to run the service: to receive, store, process, index, back up and deliver that mail to you and to the assistants you authorise, and to derive the metadata, text and hints the service produces. We claim no other right in it. We keep mail only as long as the retention rules you can see and set, and delete it permanently after that. You can export everything and delete your account at any time; deletion completes within 24 hours, and copies in backups are purged within 35 days. Our privacy policy describes how we handle data and is part of these terms.

7. Our property

The service, its software, design, documentation and name are ours or our licensors’. Subject to these terms we grant you a limited, revocable, non-exclusive, non-transferable licence to use the service for your own purposes. Any feedback you give us may be used freely without obligation. Nothing transfers ownership of anything.

8. Third-party services

Parts of the service are provided by others: Cloudflare (receiving, compute, storage, image text extraction), Neon (database), Clerk (sign-in and account emails), Stripe (payments), and the assistant platforms you choose to connect. Their availability and terms are theirs. We choose them with care, but an outage or change on their side may affect the service.

9. Private beta; the service as is

The service is in private beta: features may change, break or be withdrawn, and data limits may be adjusted. To the fullest extent the law allows, the service is provided “as is” and “as available”, without warranties of any kind, express or implied, including merchantability, fitness for a particular purpose, title, non-infringement, and any warranty arising from course of dealing or usage. We do not warrant that the service will be uninterrupted, error-free or secure, that mail will always be received or retained, that categories, spam scores or extracted text are accurate, or that an assistant will behave. We aim for 99.9% availability of receiving and keep nightly backups, but you must not rely on Echos as the only copy of anything that matters. Some jurisdictions do not allow certain disclaimers; in those, the disclaimers apply to the extent permitted.

10. Limitation of liability

To the fullest extent the law allows, Pudding App Inc and its officers, directors, employees, contractors and suppliers will not be liable to you for any indirect, incidental, special, consequential, exemplary or punitive damages, or for lost profits, revenue, data, goodwill or business opportunity, arising out of or related to the service or these terms, however caused and under any theory of liability, even if advised of the possibility. Our total liability for all claims arising out of or related to the service or these terms will not exceed the greater of the amounts you paid us in the twelve months before the event giving rise to the claim, or one hundred US dollars ($100). These limits do not apply to liability that cannot be limited by law, and they apply even if a remedy fails of its essential purpose.

11. Indemnification

You will defend, indemnify and hold harmless Pudding App Inc and its officers, directors, employees, contractors, agents and suppliers from and against any and all claims, demands, suits, proceedings, liabilities, damages, losses, judgments, settlements, penalties, fines, costs and expenses (including reasonable attorneys’ fees) arising out of or related to: (a) your use of the service or of any mail, data or output obtained through it; (b) anything done under your account, including by any assistant, script, key or person you authorise or allow; (c) your breach of these terms, of the acceptable-use rules, or of any law or regulation; (d) your infringement or violation of any right of a third party, including intellectual-property, privacy and publicity rights; (e) any dispute between you and any third party, including a sender of mail or an assistant provider; or (f) any content you receive, store, process or export through the service. We may take over the defence and control of any matter subject to indemnification at our own expense, in which case you will cooperate with us; you will not settle any such matter without our written consent. This section survives termination.

12. Dispute resolution: individual arbitration, no class actions

Informal resolution first. Before starting any formal proceeding, you and we agree to try to resolve any dispute informally: send a written description of the dispute to hello@echos.fyi (or we will send one to your contact email), and both sides will make a good-faith effort to resolve it within 60 days.

Binding arbitration. If a dispute is not resolved informally, you and Pudding App Inc agree that any dispute, claim or controversy arising out of or relating to these terms or the service — including its formation, breach, termination, enforcement, interpretation or validity, and the scope of this arbitration agreement — will be resolved by binding individual arbitration administered by the American Arbitration Association (AAA) under its Consumer Arbitration Rules (or Commercial Rules for business users), as modified by these terms. The Federal Arbitration Act governs this section. The arbitrator, not a court, decides all questions of arbitrability except as stated below. Arbitration will take place in San Francisco, California, or by video or on written submissions where the rules allow; an award may be entered in any court with jurisdiction. Each side bears its own fees except as the rules or law provide; if you cannot afford AAA’s consumer filing fee we will pay it.

Class action and jury waiver. You and we agree that each may bring claims against the other only in an individual capacity, and not as a plaintiff or class member in any purported class, consolidated, collective or representative proceeding. The arbitrator may not consolidate more than one person’s claims or preside over any form of class or representative proceeding, and may award relief only to the individual party seeking it. If this class-action waiver is found unenforceable for a particular claim, that claim (and only that claim) will proceed in court, and the rest will still be arbitrated. To the extent the law allows, you and we each waive the right to a jury trial.

Exceptions. Either side may bring an individual claim in small-claims court, and either side may seek an injunction or other equitable relief in court to protect intellectual property or to stop unauthorised use of the service.

Opt-out. You may opt out of this arbitration agreement by emailing hello@echos.fyi with the subject “Arbitration opt-out”, your account address and your name, within 30 days of first accepting these terms. Opting out does not affect any other part of these terms.

Court venue if arbitration does not apply. Any dispute not subject to arbitration will be brought exclusively in the state or federal courts located in San Francisco County, California, and you consent to their jurisdiction.

13. Termination

You can delete your account whenever you like from Settings. We may suspend or close your account or the service with 30 days’ notice, or immediately for a breach of section 3, non-payment, a lawful demand, or to protect the service or others; where practical you will be able to export your data first. Sections 6 (as to our licence to complete deletion), 7, 10, 11, 12, 14 and 15 survive termination.

14. Governing law and compliance

These terms are governed by the laws of the State of California and the United States, without regard to conflict-of-law rules, except that section 12 is governed by the Federal Arbitration Act. You must comply with US export-control and sanctions laws and confirm that you are not on a US government restricted list and not located in a country subject to comprehensive US sanctions.

15. General

These terms and the privacy policy are the entire agreement between you and us about the service and replace any earlier agreement. If a provision is found unenforceable it is limited to the minimum extent necessary and the rest stands. A failure to enforce a provision is not a waiver. You may not assign these terms; we may assign them in a merger, acquisition or sale of assets, with notice on the dashboard. Notices to you go to your contact email or the dashboard; notices to us go to hello@echos.fyi or Pudding App Inc, San Francisco, CA, USA. We are not liable for delay or failure caused by events beyond our reasonable control. We may change these terms; the date at the top moves, and the dashboard tells you before a change that materially affects you takes effect. Continuing to use the service after that is acceptance; if you disagree, delete your account before the change takes effect.
