Terms of service
The agreement for using Calendar Alarm.
These terms explain the service, your responsibilities, safety limitations, online features, and the rules for purchases and subscriptions.
1. Provider, scope, and agreement
These Terms of Service govern Calendar Alarm Clock Reminder (also called Calendar Alarm), its optional online features, and this website. The provider is 4LIMIT Sports GmbH, Hahner Str. 80, 64354 Reinheim, Germany. Contact: calendar.reminder.zzapp@gmail.com.
These Terms apply only when they have been made available before or when the agreement is formed and are validly incorporated under applicable law. They bind you when you accept them in a manner recognized by applicable law; downloading or continuing to use the app alone does not override mandatory incorporation or consent requirements. If you do not accept applicable Terms, do not use the affected service. Mandatory consumer rights remain unaffected.
Google Play and any calendar, map, weather, or account provider you choose may apply separate terms to its own service. Those terms do not replace these Terms for Calendar Alarm.
2. Eligibility and authority
You must be legally capable of entering this agreement. If you are below the applicable age or otherwise cannot contract independently, a parent or legal guardian must authorize your use of online features and any purchase.
If you use the app for an organization, you confirm that you are authorized to act for it. Consumer protections continue to apply wherever the law treats you as a consumer.
3. The service
The app provides calendar views, event alarms, a standalone alarm clock, timers, a stopwatch, weather, widgets, direct calendar synchronization, and optional AI-assisted features. Features can vary by device, Android version, country, app version, entitlement, provider availability, or granted permission.
The free version may include advertising. Pro removes in-app ads while a valid entitlement is active and may unlock additional personalization or alarm-presentation features. Some legacy users may have a supported one-time Pro entitlement.
Internet access, Google Play Services, a compatible provider, or special Android access can be required for a particular feature. The app does not provide emergency monitoring, professional advice, or a guaranteed communications service.
4. License and intellectual property
Subject to these Terms, we grant you a personal, limited, non-exclusive, non-transferable license to install and use the app for lawful personal or internal business purposes. The license may be suspended or ended only as described in these Terms or permitted by law.
The app, website, source code, design, branding, illustrations, and original content are owned by 4LIMIT or its licensors. No right is granted except the limited right to use the service. Open-source and third-party components remain subject to their own licenses.
5. Permissions and device configuration
You choose which permissions and system privileges to grant. A feature will not work, or may work less reliably, if required access is refused or revoked.
Alarm delivery can be affected by volume, Do Not Disturb, notification channels, exact-alarm and full-screen permissions, battery optimization, background restrictions, device shutdown, manufacturer firmware, restored settings, and Android updates. Use the in-app troubleshooting checks and test alarms after installation, migration, permission changes, or major system updates.
6. Important alarm and safety limitation
Do not use Calendar Alarm as the sole safeguard for emergencies, medical or medication-critical reminders, personal safety, legal deadlines, transportation safety, industrial systems, or any situation where a missed, late, or incorrect alarm could cause death, injury, or serious loss.
Use an independent backup reminder whenever timing is critical. Always confirm that the device is powered, audible, permitted to run in the background, and configured for the alarm behavior you expect.
7. Calendar synchronization and backups
Synchronization can create, modify, duplicate, restore, or delete calendar data locally and at a connected provider. Conflicts, provider errors, rate limits, expired credentials, recurrence differences, unsupported reminders, delayed background work, network failures, or incompatible properties can affect results. Some Outlook recurrence changes or multiple reminders, for example, may not be supported and can be restored to the provider version.
Review synchronized data and maintain an appropriate independent backup. Removing a connection from Calendar Alarm removes local credentials and mirror records; it does not necessarily delete remote data or revoke the provider authorization.
8. AI-assisted features
The event extractor and Help Chat use artificial intelligence. They can misunderstand images, PDFs, printed text, settings, dates, time zones, locations, or your intent. The event extractor may infer missing information. Output is informational and can be incomplete, biased, or wrong.
You must review every generated event, date, time, time zone, location, reminder, and settings proposal. AI output is not medical, legal, financial, safety, employment, or other professional advice. Help Chat cannot change a setting unless you tap Apply, and the app validates each proposal again.
Do not submit special-category, criminal-conviction, confidential, or safety-critical data to an AI feature. Submit another person's content only when you have the necessary rights, authority, and lawful basis. The Privacy Policy explains cloud processing and retention.
9. Weather, map, and route information
Weather, geocoding, place, route, traffic, and map information comes from third parties and may be delayed, unavailable, or inaccurate. It is not intended for emergency, aviation, marine, agricultural-safety, medical, or other safety-critical decisions. Verify important conditions with an authoritative source.
10. Your content and third-party rights
You keep ownership of content you enter, select, or connect. You give 4LIMIT and the relevant service providers only the limited permission needed to provide your requested feature, secure the service, enforce quotas, retain the latest text-extraction troubleshooting record as described in the Privacy Policy, troubleshoot support issues with your authorization, and comply with law. This permission ends when the purpose and applicable retention period end.
You confirm that you have the rights and lawful authority needed for images, documents, printed emails or chats, calendar data, attendee information, and other material you submit or process. Do not use the app to violate privacy, confidentiality, copyright, employment, or other third-party rights.
11. Connected and third-party services
Google, Microsoft, Apple and other CalDAV providers, WeatherAPI, Maps and Places, Firebase, Vertex AI, AdMob, Vercel, Google Play, and other linked services are governed by their own availability, terms, and privacy notices. We do not control an independent third party's outage, account suspension, policy change, content, or data handling.
We remain responsible for our own selection, configuration, and legally required oversight of processors. Nothing in this section excludes liability that mandatory law assigns to 4LIMIT.
12. Advertising, Pro, subscriptions, and tips
The free version may display advertising. A valid Pro subscription or supported legacy one-time Pro purchase removes in-app ads and unlocks the features shown before purchase. A separate 'Donate a coffee' purchase is a voluntary consumable tip and does not unlock Pro or other features.
Google Play displays the contracting/payment information, product, price, taxes, currency, billing period, trial or introductory offer, and renewal terms before you confirm a purchase. Subscription prices and eligibility can differ by account or region. A subscription renews automatically under the terms shown by Google Play unless cancelled before renewal. Uninstalling the app does not cancel it.
Manage or cancel a subscription through Google Play. Cancellation normally stops the next renewal while access continues through the paid period. Refunds, withdrawal rights, remedies for non-conforming digital products, and other mandatory rights follow applicable law and the store process; nothing in these Terms makes a purchase categorically non-refundable.
Where EU withdrawal law applies, consumers generally have 14 days to withdraw from a distance contract. For digital content or services supplied before that period ends, the right may expire or be reduced only under the conditions required by law, including any necessary request, express consent, and acknowledgment presented during checkout. Exercise the right against the contracting seller shown at checkout through the Google Play process (for EEA Play-billed purchases, normally Google Commerce Limited). Contact 4LIMIT for app support or for a purchase only where 4LIMIT is identified as the seller.
The app may verify purchase tokens and entitlement status through Google Play to acknowledge purchases, restore supported entitlements, and prevent fraud. If a purchase cannot be restored, contact support before buying again.
13. Acceptable use
- Do not use the app unlawfully, deceptively, or to violate another person's rights.
- Do not use calendar, contact, document, or location information to stalk, harass, unlawfully monitor, discriminate against, or profile another person.
- Do not bypass subscriptions, quotas, advertising, access controls, App Check, Play Integrity, or other security measures.
- Do not reverse engineer, redistribute, resell, or create derivative works except where mandatory law or an applicable open-source license expressly permits it.
- Do not upload malware, overload the service, probe systems without authorization, interfere with the app/backend, or use automation to evade limits.
14. Updates and service changes
We may provide functional, compatibility, and security updates. Install updates within a reasonable time after notice; failing to install an update can affect security or operation. Your statutory right to updates required to keep a digital product in conformity remains unaffected.
We may change a feature only for a valid reason described by the nature of the service, such as security or abuse prevention, changed law, Android or provider compatibility, replacing a discontinued dependency, correcting a defect, or improving existing functionality. A change will not impose an additional charge without your agreement.
Where a change negatively affects a consumer's access or use beyond a minor extent, we will provide clear advance notice on a durable medium, explain the reason and effective date, and provide any termination, refund, or continued-access right required by law. We do not promise that every optional free feature will remain available indefinitely or work on every device.
15. Suspension and termination
You may stop using the app at any time, remove connected accounts, clear app data, and uninstall. You must separately cancel any Google Play subscription.
We may restrict access to online features for a material breach, fraud, security threat, unlawful use, repeated quota circumvention, or a legal requirement. Except where urgent action is needed to protect users, the service, or third parties, we will give reasonable notice and an opportunity to remedy a remediable breach where legally required.
Ending access does not remove rights or obligations that arose before termination, including payment, warranty, privacy, intellectual-property, liability, and legal-claim provisions that by their nature continue.
16. Statutory warranty and conformity
Mandatory statutory warranty, digital-product conformity, remedy, update, withdrawal, and consumer rights remain unaffected. If the app is not in conformity, you may have rights to cure, price reduction, termination, damages, or reimbursement under applicable law.
Feature descriptions explain the intended service but are not a separate guarantee unless expressly identified as one. Third-party, network, and device limitations described in these Terms are part of the service context and do not remove mandatory remedies.
17. Liability
We are liable without limitation for intent and gross negligence; injury to life, body, or health; liability under the German Product Liability Act; fraudulent concealment; an expressly assumed guarantee; and liability that cannot legally be limited.
For slight negligence, we are liable only for breach of an essential contractual obligation whose performance is necessary for the agreement and on which a user normally relies. In that case, liability is limited to foreseeable damage typical for the agreement. Otherwise, liability for slight negligence is excluded to the extent permitted by law.
These limits also apply to our representatives, employees, and agents. They do not limit statutory consumer remedies or liability that mandatory law does not allow us to exclude.
18. Changes to these Terms
We may update these Terms prospectively for a valid reason such as a new or changed feature, security need, provider change, correction, or legal development. A change will be proportionate and will not retroactively remove accrued rights.
Where required, we will give reasonable advance notice through the app, website, store, or a durable medium and explain the effective date and your available options. If law requires your consent, the change will apply to you only after valid consent. You can stop using the service before a change takes effect, subject to separate subscription cancellation.
19. Governing law and disputes
German law applies, excluding the UN Convention on Contracts for the International Sale of Goods. For consumers, this choice does not remove mandatory protections of the law of their habitual residence. Statutory consumer venues remain unaffected. An exclusive venue at our registered office applies only where legally valid, including for merchants where the applicable procedural law permits it.
4LIMIT Sports GmbH is not willing or obliged to participate in dispute-resolution proceedings before a consumer arbitration board. Please contact us first so that we can try to resolve a concern directly.
20. Severability, no waiver, and contact
If a provision is wholly or partly invalid, mandatory law applies in its place and the remaining provisions continue to the extent legally possible. A delay in enforcing a right is not a waiver of that right.
These Terms, the referenced Privacy Policy, and any purchase terms shown before checkout form the applicable agreement for the subject they cover. Questions and support requests can be sent to calendar.reminder.zzapp@gmail.com.
