Terms and Conditions

These Terms and Conditions govern the contractual relationship between the Provider and the respective user, referred to below as the “User”, concerning use of meinsystem.app, referred to below as the “Service”. Any conflicting terms of the User are not accepted unless the Provider expressly agrees to them.

A consumer is any natural person who uses the Service for purposes that can predominantly be attributed neither to their commercial nor their self-employed professional activity. An entrepreneur is a natural or legal person or a partnership with legal capacity that uses the Service in the course of its commercial or self-employed professional activity.

Mandatory statutory provisions always take precedence. Otherwise, the following order applies in the event of contradictions: (a) individual agreements and (b) these Terms and Conditions.

The Apple Standard EULA additionally applies to the iOS or iPadOS app distributed through the Apple App Store. Apple's applicable terms also govern obtaining and using the app through the App Store. If these Terms and the Apple Standard EULA differ regarding the licensing or use of the iOS or iPadOS app, the Apple Standard EULA prevails. The applicable Google Play terms apply correspondingly to an Android app distributed through Google Play.

German law applies, excluding the UN Convention on Contracts for the International Sale of Goods. Mandatory consumer-protection provisions at the consumer’s place of residence remain unaffected. The contract is concluded in German. Unless stated otherwise during checkout, all prices are gross prices in euros including statutory VAT.

The specific scope of features is determined by the description displayed on the website, in the app or in the relevant app store before use begins or a purchase is made. The Service currently includes the following usage models:

The Provider may technically develop the Service, add features or discontinue individual features, provided the contractually owed core service is not materially impaired and Users are informed in good time.

Use requires a compatible device with a supported app or browser version. The web app, account features, cloud sync and external integrations require an internet connection. Local features can be used offline where identified as such in the app. The User bears telecommunications costs.

Free in the native app can be used without registration and without a time limit within the displayed feature limits. Without a User account, content is stored only locally on the relevant device.

Registering for the web app does not by itself grant time-limited Pro access. Extended web access requires a Pro subscription or a trial started through the Lemon Squeezy checkout.

The yearly plan may include a 7-day trial at checkout. Payment details are required. If the subscription is not cancelled before the trial ends, the yearly price is charged. A Lemon Squeezy trial is a Pro entitlement, including cloud sync. The monthly plan does not include a trial.

Older web trials that already started without payment details remain valid until their original end date and are not a Pro entitlement for the native app.

Mobile Free and Lifetime can be used without a User account. The web app, cloud sync, cross-device use and other features identified as account-based require registration by email or Google OAuth. Details must be truthful and kept up to date. Automated access such as bots or crawlers is prohibited.

Login details must be kept confidential. The User is responsible for activity under their account and must immediately notify the Provider of suspected misuse at support@meinsystem.app.

Free: The free usage contract is concluded when use begins. This does not create a paid contract or subscription.

Lemon trial: The 7-day yearly-plan trial contract is concluded when the Lemon Squeezy checkout is confirmed. After the trial, the yearly price is charged unless the subscription is cancelled first.

Web purchase: A paid Pro contract is concluded when the User places a binding order for the selected offer through the Lemon Squeezy checkout and the purchase is confirmed. The contract and payment terms displayed during checkout are decisive.

In-app purchase:A Lifetime purchase or Pro subscription through a native app is concluded when the relevant app store confirms the purchase. The app store's terms additionally govern ordering, payment and the store entitlement.

These Terms and Conditions are available before the contract is concluded and can be viewed at /en/terms-and-conditions at any time.

Mobile Free runs for an indefinite period and can be ended at any time by deleting the local app data or uninstalling the app. A Lemon trial ends automatically; without cancellation the yearly plan then continues as a paid service.

The Pro subscription can be purchased monthly (€7.99) or yearly (€49.99) and renews for the selected billing period unless cancelled before the next renewal. A subscription purchased on the website can be cancelled through the Lemon Squeezy customer portal or by emailing info@maxantonschneider.com. After cancellation, Pro access remains active until the paid period ends.

If the Pro plan was purchased through the iOS or Android app, management and cancellation take place exclusively through the subscription settings of the respective Apple ID or Google account, not through the Lemon Squeezy customer portal or by emailing the Provider. The Provider has no direct access to these in-app subscriptions and cannot cancel them on the User's behalf.

Lifetime is a one-time purchase and does not renew. The store entitlement can be retrieved using the relevant app store's restore function where supported for the account and device used. Lifetime does not include automatic transfer of locally stored content.

The User may delete their account at any time. Account deletion does not end a subscription purchased through Apple or Google; it must also be cancelled in the relevant store. Account data is deleted within 30 days unless statutory retention duties apply. The User must delete exclusively local data on their own devices.

The right to extraordinary termination for good cause remains unaffected. The Provider may suspend or delete accounts for serious breaches of these Terms.

Unless otherwise stated, prices on our website are consumer prices including all applicable taxes.

Payments for paid subscriptions and digital products are processed by Lemon Squeezy. Lemon Squeezy acts as merchant of record and handles payment processing, tax calculation, invoicing, refunds and other transaction-related processes. The Provider supplies the Service. Lemon Squeezy’s terms and those of the selected payment provider may also apply to payment processing. Accepted payment methods are shown during checkout.

Lifetime and Pro can be purchased in the native app as in-app purchases through Apple or, once offered, Google. These purchases are processed by the relevant app store under its terms. The product name, duration, currency and final amount shown immediately before confirmation are decisive for the store purchase. Store prices may differ from prices shown on the website.

The binding final amount is displayed to the customer in the Lemon Squeezy checkout or by the selected payment provider before the order is completed.

Lemon Squeezy technically processes payments in US dollars. The amount may therefore be displayed or processed in US dollars and then converted into euros by the payment provider, card issuer or customer’s bank.

Currency conversion may use the exchange rate and incur fees of the relevant payment provider, card issuer or bank. We do not charge these and cannot influence them. The euro amount shown on a PayPal, credit-card or bank account may therefore differ slightly from the euro price shown on our website.

The decisive amount is the one shown to the customer immediately before payment is completed in checkout or by the chosen payment provider.

For subscriptions, the euro amount shown for future charges may also fluctuate slightly if a US-dollar payment is converted into euros by the payment provider, card issuer or bank.

Subscription fees are due in advance at the beginning of each billing period; Lifetime is due once. Receipts, invoices and refunds are handled through the channel used for the purchase. Website purchases are governed by Lemon Squeezy's terms and the statutory right of withdrawal (see the Information on the right of withdrawal).

If payment is overdue, the Provider may suspend Pro access until it is settled. Consumers are in default only if the invoice informed them of the consequences.

Price changes do not affect paid periods or completed Lifetime purchases. Changes for future renewal periods are communicated through the relevant purchase channel before they take effect. Where consent is required by law or the rules of that channel, the new price does not take effect without that consent. The User can cancel the subscription before the next renewal.

Consumers may have a statutory right of withdrawal when concluding a paid contract through the website. Details, deadlines, consequences and the model form are set out in the Information on the right of withdrawal.

For an in-app purchase, the technical handling of a refund or withdrawal request is governed by the relevant app store. Requests concerning Apple purchases must be submitted through Apple's designated refund channels; requests concerning Google purchases must be submitted through Google's. Mandatory statutory consumer rights remain unaffected.

Withdrawal, cancellation, account deletion and uninstalling the app are separate actions. In particular, deleting the User account or the app does not end a current app-store subscription.

• —Use the Service only for lawful purposes.
• —Do not create or distribute unlawful content.
• —Do not overload or attack the infrastructure.
• —Do not attempt unauthorised access to the Provider's systems.
• —Do not transfer, rent or sublicense the Service to third parties.
• —Use available updates and secure devices.

The Provider may suspend access where necessary to stop a breach.

The User remains the owner of content they create. The Provider receives only the non-exclusive rights of use required to provide the Service. For details on personal-data processing, see the Privacy Policy.

The User is responsible for regular data backups by export.

Users may optionally connect Google accounts through OAuth and integrate Google Calendar. Google’s terms and privacy information also apply. The Provider is not liable for outages, changes or restrictions at third-party providers.

For purchases through the iOS or Android app, the Provider also uses RevenueCat(RevenueCat, Inc.) to manage and reconcile store entitlements. For account-based Pro, the entitlement status may additionally be reconciled with the User's account. For details on the data processed and third parties involved (Apple, Google, RevenueCat), see the Privacy Policy.

Technical provision uses hosting and infrastructure providers as well as Lemon Squeezy. The Provider may use qualified agents to fulfil the contract.

Software, design, text and other elements of the Service are protected by copyright and industrial-property rights. All rights remain with the Provider unless expressly agreed otherwise.

The User receives a non-exclusive, non-transferable right to use the Service as intended. For Free, this right applies while the relevant offer is provided; for Pro, it applies for the contract term; and for Lifetime, it applies indefinitely to the purchased local Lifetime features. The relevant app store's additional licence and usage rules, including the Apple Standard EULA, remain unaffected. Reverse engineering, decompilation, resale and sublicensing are prohibited only to the extent that mandatory law does not permit them. There is no entitlement to source code.

The Provider endeavours to provide the Service with as few interruptions as possible. There is no entitlement to specific availability or response times unless individually agreed. Planned maintenance will be announced in advance where possible.

The Provider may modify the Service for valid reasons, particularly to reflect changes in law, security requirements, technical developments, operating systems, interfaces or feature development. Such modifications do not impose additional costs on consumers. Users will be informed clearly and comprehensibly. If a modification impairs access or usability to more than a minor extent, the statutory information and termination rights apply, in particular Section 327r BGB.

Statutory warranty rights apply to paid plans and purchases and are not restricted for consumers. Mandatory statutory rights also remain unaffected for free offers.

The Provider has unlimited liability for intent, gross negligence, injury to life, limb or health, fraudulent concealment of defects and under the German Product Liability Act.

For an ordinarily negligent breach of essential contractual obligations (cardinal duties), liability is limited to foreseeable, typical damage.

Liability is otherwise excluded to the extent permitted by law. For data loss caused by ordinary negligence, liability within the preceding limitation is restricted to the typical restoration cost that would have arisen if regular, appropriate backups had been made. Users should regularly use the available export functions.

The Provider is released from its obligation to perform for as long and to the extent performance is impossible or unreasonable due to force majeure, official orders, strikes, a pandemic or comparable events beyond its control.

The Provider is neither obliged nor willing to participate in dispute resolution proceedings before a consumer arbitration body. Support enquiries: support@meinsystem.app.

New contracts are governed by the version of these Terms provided when the contract is concluded. The Provider may amend the Terms for the future, particularly because of changes in law, case law, purchase channels or the Service.

Changes to an existing contract will be communicated to the User in text form where they affect the User. Where consent is required, changes do not become part of the contract solely through silence. Mandatory statutory rights, paid periods and completed Lifetime purchases remain unaffected. Modifications to the digital product are additionally governed by Section 13.

The Provider’s registered office is the place of jurisdiction for disputes with merchants, legal entities under public law or special funds under public law. The statutory jurisdiction rules apply to consumers.

Changes and additions to the contract must be made in text form, for example by email, unless the law prescribes a stricter form.

If individual provisions are invalid, the remainder of the contract remains valid. The invalid provision is replaced by a permissible provision that most closely reflects its economic purpose.
