Terms of service

Deeperer is operated by Lumman Ltd, registered in England and Wales (No. 15425759), 86-90 Paul Street, London, EC2A 4NE, United Kingdom. Lumman Ltd is the party to these terms and the provider of the service. Reach us at in@deeperer.com.

Paid plans and balance top-ups are sold by Polar as Merchant of Record. Polar sells the plan, takes the payment, accounts for the tax on it and issues any refund. Your payment transaction is with Polar and is governed by Polar's own terms as well as these; the service itself is provided by Lumman Ltd under these terms.

Creating an account, starting a research run, or using the API or MCP endpoint means you accept these terms. If you accept them for an organisation, you confirm you may bind it, and "you" then means that organisation.

Two further documents form part of this agreement: the Acceptable Use Policy, which sets out what the service may not be used for, and the Data Processing Agreement, which governs our handling of personal data you put into the service. Where a signed order form or enterprise agreement conflicts with these terms, that document prevails for the customer that signed it.

You must be at least 18 years old to hold an account. Sign-in is by Google, by a one-time link sent to your email address, or by a passkey you add; we never ask for or store a password. Signing in for the first time creates your account. Email sign-in refuses disposable addresses.

You are responsible for what happens under your account, for keeping access to your mailbox, your Google account and your passkeys secure, and for the people you invite into a workspace. Each workspace has exactly one billing owner at any time and at least one administrator.

You can type your question on the home page before you sign in. What you typed stays in your browser and carries into your workspace once you sign in.

Deeperer turns a research request into a written report. You describe what you need in a conversation; the platform plans the report, searches for what each section rests on, reads and quotes the pages it keeps, writes the report from those quotes, and publishes it at a canonical URL. Depending on your plan you can also apply a workspace brand voice, keep a workspace knowledge base that every run reads, generate presenter notes, export to PDF, DOCX and markdown, and read everything programmatically over the REST API or the MCP endpoint.

How a report is produced is our decision, not a setting you choose: which models run at which stage, how many passes a stage takes, and which sources are consulted are all internal to the platform and change as it improves. What we commit to is the output and the standard it is held to, not the mechanism behind it.

Reports are written by software. No person at Lumman Ltd reads a report before it reaches you. Statements carry inline citations, and each one is dropped unless the run holds a passage from the page it names - but that is not human review, and none of it makes a report certain.

You must check a report against its cited sources before relying on it.

A report can be incomplete, out of date, or wrong, and a citation can point somewhere that does not support the claim as strongly as the sentence implies. What the platform guarantees is narrower: every page the run went out and found was reached, a copy of it was kept, and the passage cited is one that page carries. Your own material - uploaded files, knowledge-base items - is cited by its own name rather than by a web address, and we keep no archive of what you already hold. That is not a guarantee of accuracy, not a professional opinion, and not a substitute for your own diligence.

Nothing the service produces is legal, financial, tax, medical, investment or other professional advice, and we are not a regulated adviser in any of those fields. If you act on a report in a regulated context, the responsibility for that decision and for any advice you give on the back of it is yours.

A report is published at a canonical URL on deeperer.com by default. You are shown this before a run starts and can choose a different visibility at that point:

• Public - published at its canonical URL, open to search engines, and carrying an attribution to Deeperer.
• Unlisted - reachable by anyone holding the link, marked not to be indexed.
• Private - reachable only by members of your workspace.

You can change a report's visibility at any time afterwards. Making a public report private takes down its canonical URL and withdraws it from indexing. We cannot remove it from a third party's cache, index or archive, and we cannot recall a copy someone already took.

For every report you keep public or unlisted, you grant Lumman Ltd a worldwide, non-exclusive, royalty-free licence to host, store, reproduce, publish, index, cache and display it, and to make it available over our API and MCP endpoint, for as long as you keep it published. The licence ends when you make the report private or delete it, save for cached and archived copies outside our control. Removing the Deeperer attribution from a published report requires a plan that permits it.

You own the reports your workspace produces and the material you put in: research questions, knowledge-base content, uploads, brand voices and edits. We claim no ownership of any of it beyond the publication licence in clause 6 and the licence we need to run the service for you.

You confirm that you hold the rights to everything you submit, that submitting it does not breach anyone else's rights or any duty of confidence you owe, and that we may process it as the Data Processing Agreement describes.

Lumman Ltd owns the platform, the pipeline, the templates, the prompts and everything else that produces a report, along with the Deeperer name and marks. Nothing in these terms transfers any of it to you. Deeperer's own editorial reports, published under our brand, are ours.

Reports draw on third-party material a run finds on the open web - published pages, filings, statistics, scholarly records and news - and on files you upload or keep in your knowledge base. Those sources remain the property of their owners and are used under their own terms. We screen sources against a licence policy so that material whose licence forbids commercial use does not feed a report, and we identify ourselves honestly to every source we read, with a contactable address in the request. We do not evade access controls and we do not present ourselves as an ordinary visitor when we are not one.

The platform keeps a private archive of the pages a report cited, so a statement can be traced back to what the page said when it was read. That archive is internal evidence, not a republication: it is stored privately per workspace and is not served to readers.

When you republish a report, or part of one, you take on the obligations that come with its sources - attribution, disclaimer lines that a data provider requires, and any restriction on redistributing a particular dataset. Quotation and citation in a report do not transfer a licence to reuse the underlying material at length.

Use of the service is subject to the Acceptable Use Policy, which forms part of these terms. Breaching it is a material breach of this agreement.

In summary, and without limiting that policy: do not use the service to produce unlawful content, to build a profile of a private individual, to infringe anyone's rights, to generate output you present as human-authored where doing so would mislead, to train a competing model on our output, or to interfere with the platform or reach parts of it you have no right to.

Research is paid for out of a prepaid balance held by your workspace and denominated in US dollars. A run is charged once, when it ends, for the research it did, and the charge stands in your workspace's balance ledger in dollars. A run that ends without a report is charged only what its work cost us. There is no per-report price, because reports are not uniform: a short briefing and a deep diligence report differ in cost by an order of magnitude.

Prices are shown without VAT. Where VAT applies, Polar adds it at checkout as Merchant of Record.

• Free carries no subscription and no monthly balance. A person's first report is free, once per person, whatever plan the workspace is on: we pay for its research up to a limit we set, and where it needs more it waits for your balance like any other run. A first report that fails for a technical reason on our side does not use up the free report. Free reports can pause for the rest of a day, in UTC, once that day's are taken. API and MCP access are included and rate-limited.
• Paid plans are billed monthly in advance and add their price to your balance at the start of each billing period. Those funds belong to that period: they stop being spendable when the period ends, and an unused monthly allowance does not roll over.
• Balance you buy outright - a top-up, at any time - has no period attached. It stays spendable while your account is open, including after a subscription ends.
• Moving to a higher plan part-way through a period adds the difference between the two plans' monthly funding, scaled to how much of the period is left, and never more than you were charged for the change. Moving to a lower plan adds nothing and takes nothing back; the lower funding applies from your next period.
• Promotional credit, where we issue it, is granted once per account, has no cash value, and is not refundable.

No cost is quoted before a run starts. What a run costs is settled from its own work when it ends, and every movement stands in your workspace's balance ledger.

There is no spending limit to set: the only bound on a run is your balance, and the funding instruction in clause 11 if you have given one. A run starts only where your balance still covers what your runs already in flight may owe, and a run whose money runs out stops where it stands, spending nothing, and carries on from there once your balance covers the work still ahead of it, unless you give the order up first. A run still waiting after seven days ends where it stands and tells you why. Whatever it spent past what you held is ours: your balance never falls below nothing, and nothing you were not funded for is owed.

Each kind of money in your balance carries its own term, and your billing page states it: a monthly allowance stops when its period ends, a promotional balance carries the term stated when it is granted, and balance you bought does not stop. What a term leaves behind is recorded as expired rather than quietly removed.

Prices, plan contents and what research costs can change. A change to a recurring price takes effect from your next billing period after we tell you, and you may cancel before it applies. A change to what research costs applies from the moment it is set and never reprices work already charged.

Automatic funding is off unless you turn it on. Only a workspace's billing owner can turn it on, because it commits their card. It needs a card already on file; where none is held we charge nothing and tell you so.

When you turn it on, you set three figures:

• the balance at which funding fires, which is yours to set and not a level we hold you at;
• how much one funding event adds to the balance, from the amounts we offer;
• the most that automatic funding may add in a calendar month, in total.

All three are yours, and the two card figures sit under limits we set. A monthly figure lower than a single funding amount is refused when you set it, rather than accepted and then refusing every funding event afterwards.

What we do without you present

• When work is about to start and your balance has fallen to the figure you set, we add one funding event to it - never past your monthly figure - and the work proceeds where your balance then covers it.
• A periodic check funds any workspace already sitting below the figure it set, and settles a funding attempt an interruption left open.
• The month's room is claimed before your card is touched and given back where an attempt takes no money, so the same monthly figure is never spent twice.

What stops it

If your monthly figure is spent, or the card is refused, or a confirmation step cannot be completed, or no card is held, we charge nothing further and the work we could not fund ends with nothing owed for it. An attempt the provider has not answered for blocks a further charge rather than permitting one. After a refused or unconfirmed card we take no further automatic charge for that workspace until you pay through the ordinary payment page or the next day begins, measured in UTC. We never carry a workspace on credit.

A payment you make yourself never counts against your monthly figure. Every automatic funding event is charged and receipted by Polar like any other purchase, and appears in your workspace's balance ledger. You can change any of the three figures, or turn automatic funding off, at any time, and the change takes effect at once.

You can cancel a subscription at any time from the billing portal. Access continues to the end of the period you have already paid for, and that period is not refunded in part. Cancelling does not delete your account or your reports. Turning automatic funding off stops any further automatic charge immediately.

Unspent balance is refundable on request.

Balance already consumed by a run is not, because the research it paid for has been produced and delivered. Where an order is refunded, the funds that order added are reversed as far as they are unspent, and the reversal stops at zero rather than leaving you in debt. Refunds are issued and paid out by Polar as Merchant of Record.

If you are a consumer

Where you buy as a consumer rather than for a business, you normally have 14 days to cancel a purchase of digital content. Because a research run begins as soon as you start it and cannot be undone, you are asked to agree, at the point of purchase, that supply may begin immediately and to acknowledge that you lose the right to cancel to the extent the content has been supplied. Balance you have not spent stays refundable within the cancellation period regardless.

None of this affects your statutory rights, including your rights under the Consumer Rights Act 2015 and the Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013. Where these terms and those rights conflict, those rights win.

API keys authenticate as your workspace and are shown once. Keep them secret, do not embed them in a client application or a public repository, and revoke a key you think is exposed. Anything done with a valid key is treated as done by your workspace.

Requests are rate-limited per key and per address, and runs started over the API are billed exactly as runs started in the dashboard. Do not attempt to work around a limit by rotating keys, addresses or accounts. We may impose a limit on a workspace whose usage threatens the platform for everyone else, and will tell you when we do.

We aim to keep Deeperer available and quick, but we do not commit to an uptime figure and there is no service credit. The service depends on third-party infrastructure and on model providers, and any of them can fail or change. Where a change breaks something you depend on, we will tell you what it is.

We may add, change or withdraw features. Where we withdraw something material to a paid plan, you may cancel and we will refund the unused part of the period you have paid for.

Each of us may see the other's confidential information. Neither will use it except to perform this agreement, nor disclose it except to people who need it and are under equivalent obligations, nor keep it longer than the purpose requires. This does not cover information that is public, that the recipient already had, or that the law requires be disclosed.

Your research questions, knowledge base and unpublished reports are your confidential information. We do not read them except as needed to run and support the service, to investigate abuse, or as the law requires.

Where the service processes personal data you put into it, you are the controller and we are your processor, and the Data Processing Agreement governs that processing. Where we process personal data about you as an account holder - your identity, your billing record, your usage and our security logs - we are the controller, and the Privacy Policy explains it.

The published Data Processing Agreement applies without either of us signing anything. A countersigned copy is available on request.

You confirm that you are not a person or entity designated under United Kingdom, European Union or United States sanctions, that you are not acting for one, and that you are not located in a territory subject to comprehensive sanctions. We may refuse or withdraw service where a sanctions or export-control obligation requires it.

The service is provided as it stands. To the extent the law permits, we exclude every implied warranty and specifically do not warrant that a report is accurate, complete, current or fit for a particular decision, that the service will be uninterrupted or error-free, or that a source will remain available.

We warrant that we will provide the service with reasonable care and skill. Nothing here excludes a term the law does not allow to be excluded, and where you deal as a consumer your statutory rights are unaffected.

Neither of us excludes liability for death or personal injury caused by negligence, for fraud or fraudulent misrepresentation, or for anything else that cannot lawfully be limited.

Subject to that, and to the extent the law permits: we are not liable for a decision taken on a report without checking it against its sources; we are not liable for loss of profit, revenue, business, goodwill, anticipated saving or data, nor for indirect or consequential loss; and our total liability for all claims arising in any 12-month period is limited to the greater of the amount you paid for the service in that period and 100 US dollars.

Where you deal as a consumer, this clause applies only so far as the law allows, and your statutory remedies are unaffected.

If you use the service other than as a consumer, you will indemnify Lumman Ltd against claims, losses and reasonable costs arising from your breach of these terms or of the Acceptable Use Policy, from material you submit or publish, and from your use of a report. We will tell you promptly about any such claim, let you control its defence, and not settle it without your consent.

You may stop using the service at any time, cancel a subscription from the billing portal, and delete your account from your settings. Deletion is immediate and removes your identity, your solely-owned workspaces and their reports. It is refused where an owned workspace has other members or carries a live subscription, so that other people's work is not destroyed on one person's request: cancel the subscription or hand the workspace over first.

We may suspend or close an account for material breach of these terms or the Acceptable Use Policy, for non-payment, where the law or a sanctions obligation requires it, or where continuing would expose us or another customer to serious risk. Except where the breach is serious or unlawful, we will tell you first and give you a chance to put it right.

On termination your access ends, published reports are taken down, and your personal data is deleted on the schedule in the Privacy Policy. Export what you want to keep before you go. Clauses 7, 15, 18, 19, 20 and 24 survive.

We may change these terms as the service changes. The current version always lives at this address and carries the date it was last updated. Where a change materially reduces your rights or increases your obligations, we will tell account holders before it takes effect, and it applies from your next billing period. Continuing to use the service after a change takes effect means you accept it.

These terms and any dispute arising out of them are governed by the law of England and Wales, and the courts of England and Wales have exclusive jurisdiction. If you are a consumer resident elsewhere in the United Kingdom or in the European Economic Area, you keep the protection of your local mandatory consumer law and may bring proceedings in your own courts.

Talk to us first at in@deeperer.com. Most things are settled that way faster than any other.

These terms, with the Acceptable Use Policy and the Data Processing Agreement, are the whole agreement between us on their subject. Neither of us relies on any statement not written in them, save for fraudulent ones.

You may not transfer this agreement without our consent. We may transfer it to a group company or to a buyer of the business, and will tell you if we do. If a clause is unenforceable, the rest stands. Not enforcing a right does not waive it. Neither of us is liable for a failure caused by something genuinely outside our control. No third party may enforce these terms. Notices to us go to in@deeperer.com; notices to you go to the email address on your account.
