Terms of Service

Last updated: August 20, 2026

This is a convenience translation. The German version (AGB) is the legally binding one; the language of the contract is German.

§ 1 Scope, contracting parties

(1) These terms govern the use of the “Memexa” service (app, web dashboard, MCP endpoint, email capture; together the “service”) between Narveno, owner: Thomas Iovine, c/o flexdienst – #20454, Kurt-Schumacher-Straße 76, 67663 Kaiserslautern, Germany (“we”) and you as the user.

(2) The service is aimed at consumers and businesses; it is intended for personal knowledge management. Deviating terms of the user do not apply.

(3) The language of the contract is German.

§ 2 Description of the service

(1) Memexa is a hosted “second brain”: you store notes, documents and forwarded emails; we make them searchable, link them into a knowledge graph and make them available to you via the web dashboard and an MCP interface for AI clients of your choice.

(2) Features that use AI models (text recognition, search, link suggestions, Ask/chat) deliver automatically generated results. These may be incomplete or incorrect and do not constitute binding information or advice. Verify important results yourself.

(3) Which AI client you connect via MCP is your decision. We are not responsible for the processing of your content by the AI provider you choose (see privacy policy).

(4) We aim for a high level of availability in line with market standards; announced maintenance windows and disruptions outside our control are excluded. No specific outcome of search or AI features is owed.

§ 3 Registration and account

(1) Use of the service requires an account. Sign-in is passwordless via a magic link sent to your email address. You must be at least 18 years old or act with the consent of your legal guardians.

(2) Keep your email address up to date and protect access to your mailbox and any MCP tokens you create. You can revoke tokens at any time in the dashboard. Inform us if you suspect unauthorised use.

(3) There is no entitlement to registration; during a beta phase we may restrict access.

§ 4 Plans, prices, scope

(1) There is a free plan (“Free”) and paid plans (“Pro”, “Power”) with the limits described on the pricing page (e.g. storage volume, processed document pages per month, number of connected clients). The prices and limits displayed at the time of contract conclusion are decisive.

(2) If you exceed the limits of your plan, further processing (e.g. new document pages) may pause until the start of the next billing period or an upgrade. Content already stored remains available and exportable — including on the Free plan and after a downgrade.

(3) A time-limited free trial of the Pro plan ends automatically; it does not convert into a paid subscription without your action.

§ 5 Payment processing via Creem (merchant of record)

(1) You purchase paid plans via our payment provider Creem, which acts as “merchant of record”: the purchase contract for the subscription is concluded between you and Creem; Creem collects the fee, remits VAT and issues the invoice. We owe you the provision of the service itself under these terms.

(2) For the purchase, the terms displayed in the Creem checkout apply in addition, including the information there on withdrawal and refunds.

(3) Subscriptions renew for the selected billing period (monthly or yearly) until you cancel (§ 7).

§ 6 Right of withdrawal for consumers

(1) As a consumer, you have a statutory 14-day right of withdrawal when taking out a paid subscription. The withdrawal instructions including the model withdrawal form are provided in the checkout.

(2) If you request that the paid service starts immediately and you subsequently withdraw, you owe compensation for the value of the service provided up to the withdrawal (§ 357a BGB).

(3) You can also declare your withdrawal at any time via the withdrawal function on our website: Withdraw from contract (§ 356a BGB). We will confirm receipt of your withdrawal declaration by email without delay.

§ 7 Term and cancellation

(1) You can end the user agreement for the Free plan at any time without notice (delete your account).

(2) You can cancel paid subscriptions at any time with effect from the end of the current billing period — in the dashboard or via the Creem customer portal. After cancellation your account switches to the Free plan; § 4 (2) sentence 2 applies accordingly.

(3) Our right to terminate: we may terminate the Free plan with 3 months' notice in text form; paid plans with 1 month's notice to the end of the billing period. The right to extraordinary termination for good cause (in particular serious violations of § 8) remains unaffected. Before closing an account we will — except in cases of legal violations — give you at least 30 days to export your content.

§ 8 Your content and obligations

(1) Your content remains yours: we acquire no rights to notes, documents and emails you store in the service beyond what is necessary to provide it. You grant us the simple right, limited to the term of the contract, to store your content, process it (including text recognition, indexing, embedding generation) and display it to you.

(2) You may only submit content you are entitled to use. This applies in particular to the email-capture feature: only forward emails you have lawfully received; the data protection responsibility for the selection lies with you.

(3) It is prohibited to use the service for unlawful content (e.g. content infringing third-party rights, malware, criminal content) or for actions endangering operation (e.g. circumventing limits, automated mass access outside the MCP interface, reselling the service).

(4) In the event of violations we may block or remove affected content and, in the case of serious or repeated violations, suspend or terminate the account. We will inform you of measures and their reasons where legally permitted; you can object to a measure at hello@memexa.ai (Art. 16, 17, 20 DSA). Reports from third parties about allegedly unlawful content are received by our point of contact hello@memexa.ai.

§ 9 Changes to the service and these terms

(1) We continue to develop the service and may change it where the change is made for a valid reason (e.g. adaptation to technical or legal developments, security or functional improvements), does not cause you additional costs and is reasonable (§ 327r BGB). We will inform you in advance in text form of changes that more than insignificantly impair your access or usage options; in this case you have the statutory right of termination under § 327r (3), (4) BGB.

(2) Changes to these terms will be announced in text form at least 6 weeks before they take effect. If you do not object before they take effect, the amended terms only apply if we have pointed out the significance of your silence in the announcement and the change is reasonable for you; changes to essential obligations (service, price) always require your active consent. Price changes apply at the earliest from the next billing period; if you do not agree, your plan continues under the previous conditions until the end of the billing period and you can cancel until then.

§ 10 Warranty

For paid plans, the statutory warranty rights for digital products (§§ 327 ff. BGB) apply, including our update obligation (§ 327f BGB). For the Free plan, the statutory rules apply in accordance with its gratuitous nature.

§ 11 Liability

(1) We are liable without limitation for intent and gross negligence, for damage resulting from injury to life, body or health, under the German Product Liability Act and where we have assumed a guarantee.

(2) In cases of slight negligence we are only liable for the breach of essential contractual obligations (obligations whose fulfilment makes the proper performance of the contract possible in the first place and on whose observance you may regularly rely), limited to the foreseeable damage typical for the contract.

(3) Any further liability is excluded.

(4) Data backup: we back up our systems regularly. Independently of this, the Markdown export is available to you at any time; we are not liable for content you did not export before a deletion initiated by you.

§ 12 End of contract, export and deletion

(1) You can export your notes at any time as a Markdown ZIP archive.

(2) After you delete your account, your content is deleted; statutory retention obligations remain unaffected. Details in the privacy policy.

§ 13 Final provisions

(1) German law applies, excluding the UN Convention on Contracts for the International Sale of Goods. If you are a consumer habitually resident abroad, mandatory consumer protection provisions of your country of residence remain unaffected.

(2) For consumers, the statutory place of jurisdiction applies. If the user is a merchant, a legal entity under public law or a special fund under public law, the place of jurisdiction is Kaiserslautern, Germany.

(3) We are neither willing nor obliged to participate in dispute resolution proceedings before a consumer arbitration board (§ 36 VSBG).
