Terms of Service

This is a convenience translation. The German version is the legally binding one.

1. Provider and scope

These terms govern use of the DecksMD Pro subscription service, offered by Xherdi Lika, Gubitzstr. 6, 10409 Berlin, Germany (“we”, “us”). Full provider details are in the Imprint.

These terms do not apply to the open-source Obsidian plugin “Decks” itself. The plugin is licensed under AGPL-3.0 and works fully without DecksMD Pro; only the licence terms apply to it.

2. Contract formation via Lemon Squeezy

DecksMD Pro subscriptions are sold through Lemon Squeezy LLC acting as Merchant of Record. Lemon Squeezy is your contractual counterparty for the purchase and handles payment processing, invoicing and VAT. We provide the technical service itself.

Lemon Squeezy’s buyer terms apply additionally to the purchase and govern how withdrawal and refunds are handled. These terms apply to the service itself.

3. The service

DecksMD Pro turns your content into flashcards using AI language models. You send text, instructions and optionally PDF pages or images to our service; it forwards them to a model provider and returns the result to you.

The service covers:

• card generation from notes and selected text
• text recognition and card generation from PDF pages
• rewriting individual cards
• two quality tiers (“fast” and “quality”)

We owe you a tier of service, not a particular model. Which AI models run behind it may change at any time — for instance when a provider retires a model, quality degrades, or pricing changes. There is no entitlement to a specific model.

How we handle your content

Content you submit is processed only for the duration of the request and discarded afterwards. We do not store note content, instructions, images or generated cards, and we do not use them to train AI models. Every request we send carries an explicit flag prohibiting storage and use for training, and we route only to providers whose published policies exclude training on, or retaining, the content they receive; a provider’s actual handling is governed by its own published policies. We retain only the consumption figures needed to enforce usage limits and to bill.

To provide the service, your content is transferred to a provider based in the USA. Which recipients are involved, the legal basis for that transfer, and what we store and for how long are set out conclusively in our Privacy Policy. Where these terms and the Privacy Policy diverge, the Privacy Policy governs on questions of data processing.

Please do not submit documents relating to specific individuals — such as patient records or case notes with identifying details. See section 3 of the Privacy Policy for detail.

4. Usage limits

The service runs with consumption limits that protect us from disproportionate cost:

• a one-time free allowance so you can try it without payment details,
• a daily limit that bounds individual spikes,
• a monthly limit per account.

Limits are measured by actual processing cost, not by a fixed card count: a large PDF consumes more than a short note. When a limit is reached, the service declines further requests with a message; use resumes in the next period. Volume figures quoted on our pages are guidance based on typical usage, not a warranted characteristic.

We may adjust the limits if the cost of the models we use changes materially. We announce material changes with reasonable notice, and you may terminate with effect from the date the change takes effect.

5. Acceptable use

You agree not to use the service to:

• create or process unlawful, infringing or criminal content,
• circumvent usage limits, access controls or billing, in particular by holding multiple accounts for the same person,
• share credentials, resell the service, or offer it to third parties as your own,
• issue automated requests beyond what a single human would generate in normal use,
• enter third-party personal data or special category data (Art. 9 GDPR, e.g. health data) without a legal basis,
• submit content you do not hold the necessary rights to.

6. Suspension and termination by us

We may suspend your access or terminate the contract for cause if you materially breach section 5, if payments fail or are charged back, or if your use threatens the stability or economic viability of the service for others.

We will give notice and a reasonable opportunity to remedy where this is possible and reasonable. For serious breaches — in particular unlawful content or active circumvention of billing — we may suspend immediately. Where the suspension is not attributable to you, we refund the unused portion of any paid period pro rata.

7. Term and termination by you

The subscription runs monthly and renews automatically until cancelled. You may cancel at any time with effect from the end of the current billing period — in your account or through Lemon Squeezy’s customer portal. Access continues until the end of the paid period. No pro-rata refund is given for the current period on cancellation. On withdrawal, see Withdrawal and Refunds.

8. Immediate performance

You receive access immediately on conclusion of the contract. During checkout you therefore expressly request that we begin performance before the withdrawal period expires, and confirm that you lose your right of withdrawal once performance begins (§ 356 (5) BGB). Without that declaration, performance begins only after the withdrawal period has expired. See Withdrawal and Refunds for details.

9. AI-generated results

AI-generated flashcards can be wrong, incomplete or misleading — including when they read convincingly. Check every card against your source before studying it.

The service is a study aid. It is not suitable as a basis for medical, legal, financial or otherwise risk-bearing decisions and does not replace professional advice. We give no warranty as to the accuracy, completeness or fitness of generated content for any particular purpose, including passing an examination.

We claim no rights in the generated content. You remain responsible for the content you submit.

10. Availability

We aim for high availability but owe no specific availability. The service depends on third-party inputs (model providers, hosting, payment processing) whose outages can cause disruption. Maintenance and faults may interrupt access temporarily. Downtime of that kind does not by itself give rise to a claim for reduction, provided usability across the billing period is not materially impaired overall.

11. Prices and price changes

The price stated at the time of your order applies. We announce price changes in text form at least six weeks before they take effect, applying from the following billing period. You may terminate with effect from the date of the change. If you neither object nor terminate, the change is deemed accepted; we will point this out separately in the announcement.

12. Liability

We are liable without limitation:

• for intent and gross negligence,
• for injury to life, body or health,
• under the German Product Liability Act, and
• to the extent of any guarantee we have given.

For ordinary negligence we are liable only for breach of a material contractual obligation — an obligation whose fulfilment makes proper performance of the contract possible in the first place and on whose observance you may regularly rely. In that case liability is limited to the foreseeable damage typical for this type of contract.

Liability is otherwise excluded. None of this alters the burden of proof to your detriment. Your statutory rights as a consumer are unaffected.

13. Changes to these terms

We may amend these terms where necessary to reflect changes in law, case law or technical circumstances, provided this does not unreasonably disadvantage you. We will notify you in text form at least six weeks in advance. If you do not object within that period, the changes are deemed accepted; we will point out the significance of your silence separately in the notice. Where material parts of the contract change, you may terminate without notice.

14. Final provisions

German law applies. Mandatory consumer protection provisions of the country of your habitual residence remain unaffected.

If any provision is invalid, the remaining provisions remain effective.
