Terms of use and privacy
MEMMEM · Early access · Version 1.1 · 29/07/2026
One-sentence summary: MEMMEM runs entirely on your computer; we do not see, do not receive and cannot see your content. You buy a licence for early-access software, "as is", with liability limited to the price paid and your consumer rights untouched.
1. Identity of the controller
Owner of the software and data controller: Martin Caamano Castineira (DTHCST), Vimianzo, A Coruna, Spain. Contact: [email protected].
2. Purpose and licence
The purchase grants a personal, non-exclusive, non-transferable licence, revocable only for serious breach, over the MEMMEM application for Windows, in its early-access edition, for your own domestic or professional use. The following are prohibited: reselling, sublicensing, renting or redistributing the application; circumventing its delivery mechanisms; and using the MEMMEM or DTHCST brand without authorisation. The intellectual and industrial property of the software, brand and website belongs to its owner.
3. Nature of early access
You are acquiring a product under active development: it may contain bugs, change its interface and features, and any features announced as "on the way" are NOT part of the contract: they are intent, not a promise. Consideration for early access: a one-time payment with application updates included for as long as the product is maintained.
4. Privacy and data protection (GDPR and Spanish LOPDGDD)
4.1 The design principle: your data never reaches us
- MEMMEM applies privacy by design and by default (art. 25 GDPR): the processing of your conversations, memories and files takes place locally on your device. DTHCST does not receive, store, access or have any way to access that content. In respect of it, we are neither controller nor processor: the only one who processes it is you.
- The application includes no telemetry, no analytics and no advertising identifiers regarding your content.
4.2 The only data we do process
- Newsletter email (if you provide it voluntarily): legal basis, your consent (art. 6.1.a GDPR). Purpose: to notify you of product news. Retention: until you unsubscribe (just reply to any email asking to be removed).
- Purchase data (name, email, amount): processed by our store (the Shopify platform) as part of the sale contract (art. 6.1.b GDPR) and its payment gateway. We never see or store full card details. Retention: the legal tax and accounting periods.
- The website chat assistant processes the question you type in order to answer you; do not give it personal data: it does not need any.
4.3 Your rights
You may exercise access, rectification, erasure, objection, restriction and portability by writing to the email in point 1. If you believe we have not handled it properly, you may lodge a complaint with the Spanish Data Protection Agency (aepd.es).
4.4 Cookies
This website uses no tracking or advertising cookies. The only thing stored in your browser is your language preference (local storage, exempt from consent as it is strictly functional).
4.5 Your responsibility as a user
Since all your content lives on your device: backups, disk encryption and control of who accesses your computer are your responsibility. You also undertake to import only conversations that are your own or that you are entitled to use, respecting the terms of the source services and the rights of any third parties appearing in them.
5. Warranties and conformity
The software is provided "as is" and "as available". We do not guarantee uninterrupted or error-free operation, universal compatibility, or the continuity of third-party export formats (ChatGPT, Claude, Gemini or others): if a third party changes its format, the affected feature may stop working until it is updated. All of the above is without prejudice to the legal guarantee of conformity of digital content and services that protects consumers (arts. 115 and following of the Spanish LGDCU): if the app is not conform, you have the right to repair, price reduction or termination as provided by law.
6. Limitation of liability
To the maximum extent permitted by law: (a) DTHCST is not liable for data loss, loss of profit, reputational harm or indirect damages; (b) total aggregate liability is limited to the amount actually paid for your licence; (c) nothing limits liability for wilful misconduct, gross negligence, or the non-waivable rights of the consumer. Force majeure: we are not liable for breaches caused by circumstances beyond our reasonable control.
7. Withdrawal and refunds
Digital content without a physical medium: by starting the download you expressly consent to immediate performance and acknowledge the loss of the right of withdrawal (art. 103.m of the Spanish LGDCU). Beyond the legal position, our house policy: if it does not work for you and we cannot fix it, write to us and we will resolve it reasonably, including a refund.
8. Miscellaneous
If any clause is declared void, the rest remains in force. Failure to exercise a right is not a waiver. We may update these terms by publishing the new version on this page (with a new date); changes do not reduce rights already acquired over your licence. Governing law: Spanish. Jurisdiction: for consumers, the courts of your domicile in Spain; otherwise, the courts of A Coruna.
