Terms of Service

1. Who we are, and what you are agreeing to

Extended Memory ("the Service") is provided by BIT1 LLC, a Washington limited liability company ("we", "us").

By creating an account, or by continuing to use the Service after we publish a new version of these terms, you agree to them. This applies to the free plan as well as the paid ones — the free plan is a real service with real costs behind it, and the same rules govern it.

If you do not agree, do not create an account. If you already have one, you may stop using it at any time (see §12).

2. Who may use it

You must be at least 16 years old to have an account. If you are under the age of digital consent where you live, you may not use the Service. We do not knowingly collect information from children — see §B9.

You are responsible for everything done through your account.

3. What the Service does

In plain terms:

• It stores things you capture. Photographs, scanned documents, PDFs, files, notes, to-dos and saved links. The app keeps a copy on your device and syncs it to our servers.
• It reads what you store, automatically. When something arrives, we run it through automated systems that write a short description of it, extract the text on it, suggest tags, and pick out details such as dates, a vendor or an amount. This is what makes a photograph of a letter findable by what the letter says.
• It lets you search and ask questions. You can search your library, and you can ask a question in plain language and get an answer drawn from your own items, with the items it used shown beneath the answer.
• It can be shared with a household. You can invite other people into your account. See §5, and read it — it is the part people are most often surprised by.
• It can receive documents by email. Each account can be given a private save-address; anything emailed to it becomes an item in the library.
• It reminds you about dates it found on your documents, such as an expiry. See §7 for why you should not rely on those without checking.

The Service is a filing and recall tool. It is not a legal, tax, medical, financial or professional advisory service, it is not a system of record, and it is not a backup service. Keep your own copies of anything you cannot afford to lose.

4. Your account

Choose a strong password and keep it to yourself. Tell us promptly at info@extendedmemory.app if you think somebody else has got into your account. We are not responsible for losses caused by somebody using your credentials with your knowledge or through your failure to keep them safe.

5. Households and sharing — what other members can see

If you invite somebody into your account, or accept an invitation into somebody else's:

• By default, every member can see the entire library. The permissions you set on an invitation control what somebody may *add, edit or delete* — not what they may *look at*.
• Anything you add is visible to every other member unless you mark it otherwise, including documents you add after they joined.
• You can keep one of your own documents to yourself. Each document has a "Who can see this" setting, and choosing *Only me* removes it from every other member's view — including from their search results and from anything the assistant tells them. You can change it back at any time. You can only set this on documents you added yourself; you cannot make somebody else's document private, and you cannot un-private theirs.
• What "Only me" does not mean. It is a boundary between you and the people you share the library with. It is not a boundary between you and us: a private document is still stored on our systems, still read by the automated processing described in §7, and still handled by the processors listed in §B4, exactly as any other document is. If that distinction matters to you, do not put the document in the Service.
• If you make a document private after somebody has already seen it, we remove it from their copy of the library going forward. We cannot undo the fact that they saw it, and we cannot reach anything they saved, exported or photographed while it was shared.
• The account owner can remove members, change what they may do, and invite others.
• An invitation code is a key. Anyone holding a valid, unexpired code can join the household. Treat one like a house key: do not forward it, and revoke it in the app if it goes astray.

If you are joining somebody else's household, understand that the owner controls the account. Leaving is always available to you (§12).

6. Plans, payment and cancellation

The Service has a free plan and paid plans. Each plan has published limits on how much you may store, how many questions you may ask in a billing period, and how many people may share the account. Current limits and prices are shown in the app before you subscribe.

• Where you pay. Subscriptions bought through the Apple App Store or Google Play are billed by them, under their terms, and managed in your store account. We do not see your card details.
• Renewal. Subscriptions renew automatically until cancelled. Cancel through the store at least 24 hours before the renewal date.
• Refunds are handled by the store you bought from, under its policy.
• If you cancel, your paid plan runs to the end of the period you have already paid for, and does not renew. Your library is not deleted — the account becomes a free account and keeps everything it holds. But if what you have stored is over the free plan's limits, you cannot add anything new until you delete down to them or resubscribe, and the dormant-account rule in §11 applies to your account like any other free account from then on. If you want your data gone rather than kept: Account → Security → Close account in the app deletes your account and everything in it — and then cancel the subscription in your store as well, because closing the account does not stop the store from billing; only cancelling with the store does.

• If you downgrade to a plan smaller than what you have stored, nothing is deleted — but you cannot add anything new until your library fits the new plan's storage limit. Delete items until it does, or move back up. Account → Usage in the app shows exactly how much you are storing against your plan.

• We may change prices and limits. We will tell you at least 30 days before a change affects a plan you are on, and you may cancel.

7. Artificial intelligence, and what it gets wrong

Read this section. It describes the single most important limitation of the Service.

The Service uses automated systems, including large language models and computer vision, to read your documents, describe them, extract details from them, and answer your questions. These systems are probabilistic. They produce a most-likely answer, not a verified one.

That has consequences you need to plan around:

a. Extracted details may be wrong. A date, an amount, a reference number, a vendor name, an expiry or a total that the Service shows you was *read by a machine from an image*. It may be misread, misattributed, taken from the wrong line, or invented outright. Handwriting, poor lighting, unusual layouts, multi-page documents, tables and languages other than the one the document appears to be in all make this more likely.

b. Answers may be confidently wrong. When you ask a question, the answer is generated from your items. It may state something that no document supports, combine details from two documents into one false statement, or omit the very item that would have answered you. This is commonly called "hallucination", and it does not announce itself — a wrong answer reads exactly like a right one.

c. Confidence scores are not probabilities. Where the Service indicates how sure it is about something, that indication is itself produced by the same sort of model. It is a hint, not a measurement.

d. Search may not find what is there. An item may exist in your library and not appear in an answer or a search result.

e. Reminders are not guarantees. If the Service reminds you that a document expires on a date, that date was extracted automatically and may be wrong or missing entirely. We do not promise to remind you of anything, and a missed reminder is not a breach of these terms.

What we ask of you

Always open the original document and check it yourself before you rely on anything the Service tells you — before you pay an amount, meet a deadline, renew a passport, submit anything to an authority, make a medical, legal or financial decision, or act on anything that matters. The original is stored in your library and is always one tap away. It is the source of truth. The Service's reading of it is not.

Do not use the Service as your only record of a deadline, an obligation or an entitlement.

We are not liable for any loss arising from your reliance on automatically generated descriptions, extracted details, reminders or answers without checking the underlying document. This is not us disclaiming a defect: it is an inherent property of the technology, and it is why the original is always kept and always shown.

What we do about it

• We keep your original file unaltered, always, and show you which items an answer came from so you can check it.
• We tell the model to answer only from your own items and to say when it cannot find something. This reduces invention; it does not eliminate it.
• You can correct the description, title, tags and expiry date of anything in your library, and your correction wins: the automated systems never overwrite what a person wrote, including on re-analysis, and clearing a generated description keeps it cleared.
• Some extracted details (an amount, an individual date the engine read) cannot yet be edited in the app. Treat those as the engine's reading, not a record — the document itself is one tap away.

8. Your content, and the permission you give us

Your content is yours. We claim no ownership of anything you put into the Service.

To operate the Service we need your permission to do specific things with it, and only those things: to store it, back it up, transmit it between your devices and our servers and to the members of your household, and to process it through the automated systems described in §3 and §7 so that it can be described, indexed and searched. This permission is worldwide and royalty-free — because servers and networks are — and it is limited to running the Service for you. It ends when you delete the content or close your account.

We do not use your content to train artificial-intelligence models, and we do not permit our providers to (see §B5). We do not sell it. We do not use it for advertising.

You confirm you have the right to store what you store.

9. What you may not do

Do not use the Service to store or transmit anything unlawful; to store material you have no right to hold; to break, probe or overload it; to get around plan limits; to resell it; or to build a competing dataset by bulk extraction. Do not attempt to reach another household's data.

Automated bulk uploading beyond ordinary personal use may be rate-limited or suspended.

10. Availability, changes and beta features

We aim to keep the Service running but we do not promise any particular uptime, and we may change, suspend or withdraw features. Some features may be labelled beta or preview; those may change or disappear, and may be less reliable. We will give reasonable notice before removing something you materially depend on, unless we cannot for legal or security reasons.

11. Dormant free accounts — your library may be emptied

This is unusual and we want it read, not buried.

If an account is on the free plan and nobody has opened it or used it for 365 consecutive days, we will empty its library: every stored item is deleted and cannot be recovered.

Before that happens:

• We email a first warning 30 days before, and a final warning 7 days before, to the account owner's address.
• We only proceed if the final warning was actually sent and accepted for delivery, and at least 7 days have passed since.
• Any activity resets the clock to zero — opening the app on any device, by any member, an email arriving at the save-address, anything at all.

What goes is the *contents*. Your account, your household and your sign-in remain, so you can come back and start again — to an empty library.

Paid accounts are never emptied this way.

The reason is cost: storage is spent continuously and never reclaimed, and an abandoned free library accumulates forever against no revenue. Bounding that is what keeps the free plan free for everyone using it.

12. Ending it

You may stop at any time.

• Delete individual items in the app. They go to Trash first, and are destroyed when you empty it.
• Leave a household you were invited into, at any time.
• Close your account entirely — Settings → Security → Delete account. See §B8 for exactly what that destroys.

We may suspend or end your access if you materially breach these terms, if we must for legal reasons, or if your use threatens the Service or other users. Except where the breach is serious or unlawful, we will warn you first and give you a chance to fix it, and we will give you a reasonable opportunity to export your content before it is deleted.

13. Disclaimers

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, accuracy, and non-infringement.

We do not warrant that the Service will be uninterrupted, error-free, or that any output, description, extracted detail, reminder or answer will be accurate or complete (see §7).

Nothing here excludes liability that cannot lawfully be excluded — including, in many places, liability for death or personal injury caused by negligence, for fraud, and consumers' statutory rights, which are unaffected.

14. Limitation of liability

To the fullest extent the law allows:

• We are not liable for indirect, incidental, special or consequential loss; for lost profits, revenue, goodwill or anticipated savings; or for loss or corruption of data, which is why you should keep your own copies of anything critical.
• Our total liability for all claims in any 12-month period is limited to the greater of the amount you paid us in that period and USD 50.
• We are not liable for loss arising from your reliance on automatically generated output without checking the source document (§7).

15. Your indemnity

You will indemnify us against claims arising from content you store that you had no right to store, and from your use of the Service in breach of §9.

16. Changes to these terms

We may update these terms. Each version has a date, and the app records which version you accepted.

When a change materially affects your rights or obligations, we will show you the new terms in the app and ask you to accept them before you carry on, and we will give at least 30 days notice where the change disadvantages you. Minor corrections take effect on publication. If you do not accept a material change, you may close your account; §12 and §B8 apply.

17. Law and disputes

These terms are governed by the laws of the State of Washington, USA, without regard to its conflict-of-laws rules, and the state and federal courts located in King County, Washington have exclusive jurisdiction — except that if you are a consumer, you keep the protection of the mandatory law of the country you live in, and may bring proceedings there.

18. Odds and ends

If a provision is unenforceable, the rest survives. Our not enforcing something is not a waiver of it. You may not assign these terms; we may, to a successor of the business, on notice to you. These terms and the documents they reference are the whole agreement between us.
