Legal Terms of Service

These Terms of Use (“Terms”) govern your use of the tDo mobile application on iOS and Android, the optional cloud features (sharing, joining, AI generation), and tDo Premium. They are a contract between you and Xinger Solutions GmbH, Seefeldgasse 5, 3462 Absdorf, Austria (“we”, “us”). They do not replace the website imprint.

​

By installing or using tDo, you agree to these Terms. Cloud features also require an explicit in-app acceptance of the Privacy Policy and these Terms. If you do not agree, do not use tDo, and do not enable cloud features.

The full Terms are this page. The app opens this URL instead of storing a separate copy of the text.

​

1. Who may use tDo

You must be able to enter into a contract under the law of your country. If you are under 16, use tDo only with a parent or guardian, and do not enable personalized ads or cloud features on your own.

tDo is offered as a consumer app. If you use it for a business, you confirm you have authority to bind that business, and the business is the “you” in these Terms.

​

2. The service

2.1 Local app

tDo lets you create checklists and to-dos stored on your device. Local use does not require an account.

​

2.2 Sharing

Sharing is optional. If you share a list you created:

• we create an anonymous device ID on our server

• that list is uploaded and kept in sync for people who enter the code and PIN

• anyone with both values can see and change the list

• you may only share lists you created yourself

• you must not share a code and PIN with people who should not have access

Joining a list uses the same anonymous ID and stores a copy on your device, kept in sync while sharing stays active.

Sync uses last write wins. If two people edit at the same time, the later write can overwrite the earlier one. We do not guarantee conflict-free merging.

Stopping sharing: the code stops working. Others keep their local copy; it no longer syncs. Deleting a list only on your device does not remove it for everyone else.

Shared list content is not end-to-end encrypted. Treat the code and PIN as a key to that list. Copying them to the clipboard or sending them in a chat is your responsibility.

​

2.3 AI generation

“List with AI” sends your description to our server and to Groq, which runs a language model to propose a list name and tasks. You are interacting with an AI system. Output is machine-generated. It can be wrong, incomplete, biased, or unsuitable. You are responsible for reviewing it before you rely on it. Do not submit unlawful prompts or other people’s personal data without a legal basis. We may rate-limit this feature.

​

2.4 Ads and Premium

The free version may show banners and interstitials. tDo Premium is an auto-renewing subscription that removes ads. Premium is not required for local lists or for sharing.

​

2.5 Availability

We do not guarantee uninterrupted cloud service. Planned maintenance or outages can pause sync and AI. Local lists keep working on the device. We may change, limit, or discontinue cloud features with reasonable notice where practicable.

​

3. Your responsibilities

You agree that you will:

• use tDo only in accordance with law

• not upload or share unlawful, defamatory, hateful, or infringing content

• not share malware, spam, or content that exploits children

• not probe, overload, scrape, or disrupt the server

• not bypass PIN lockouts, rate limits, or access controls

• keep code and PIN confidential except with people you intend to give access

• not present tDo or our trademarks as your own product

We may lock a share link, refuse a request, remove hosted content, or disable an anonymous account if we reasonably believe these rules are broken or if we must do so by law.

Too many wrong PIN attempts temporarily lock that share link (currently after 5 failures, for 15 minutes).

​

4. User content

You keep any rights you have in list names and task text you create (“User Content”).

You grant us a non-exclusive, worldwide licence to host, copy, transmit, and display User Content only as needed to operate the features you use (local storage on your device is under your control; shared content is stored and synced on our server and delivered to members of that list). This licence ends for server copies when sharing of that list ends and remaining copies are deleted, except for backups and audit logs for a limited time, and except for copies that other users still keep on their devices.

You confirm that you have the rights needed to share that content, and that sharing it does not violate others’ privacy or IP rights.

We do not claim ownership of your lists.

​

5. tDo Premium (in-app purchases)

5.1 What you buy

tDo Premium is a subscription sold through the Apple App Store or Google Play, not as a direct charge by us on a website.

Plan: tDo Premium monthly
Length: 1 month, then renews

Plan: tDo Premium yearly
Length: 1 year, then renews

Current prices, currency, and any introductory offer (if we add one later) are shown in the paywall and in the store before you confirm. There is no free trial unless the store screen for your country expressly says so at the time of purchase.

Premium removes ads and ad interruptions. It does not add extra cloud storage quotas beyond what the free app already offers for sharing. Premium works on the devices that use the same store account after you restore purchases.

Payment is charged to your Apple ID or Google account at confirmation of purchase.

​

5.2 Store as seller

Apple or Google (as applicable) is the merchant for the purchase. Their terms and refund rules apply in addition to these Terms:

• Apple Licensed Application End User License Agreement: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

• Apple Media Services terms: https://www.apple.com/legal/internet-services/itunes/

• Google Play terms of service: https://play.google.com/about/play-terms/

​

5.3 Auto-renewal (required store language)

The subscription renews automatically unless you cancel at least 24 hours before the end of the current period. Your account is charged for renewal within 24 hours before the period ends. After purchase, you can manage or turn off auto-renewal in your store account settings:

• Apple: Settings > [your name] > Subscriptions

• Google: Play Store > Payments & subscriptions > Subscriptions

Canceling stops the next renewal. You keep Premium until the end of the period you already paid for.

tDo also offers Restore purchases and Manage subscription in Settings. Restore is required after reinstall or device change because tDo has no email login.

​

5.4 Cooling-off (EU/EEA/UK consumers)

For a distance contract, the FAGG / Consumer Rights Directive may give you a 14-day right of withdrawal.

tDo Premium is a digital service billed by Apple or Google. To stop billing you must cancel in the store as in section 5.3. Refunds of store charges are handled by Apple or Google under their policies.

If you ask for the service to start immediately (ads removed at once), EU rules on digital services still apply: the right of withdrawal for a service that runs over a period typically does not disappear at the first second of use. If you withdraw during the period, you may have to pay for the time already used, unless the trader failed to inform you as required. We inform you here that Premium starts at once when the store purchase succeeds.

To tell us you withdraw, email office@xinger.org with your store platform and approximate purchase date. We cannot reverse an Apple or Google charge ourselves; you still need the store’s cancel/refund tools.

Model withdrawal wording (optional):

I hereby withdraw from the tDo Premium subscription contract concluded on [date], store account on [iOS / Android]. Name / device as far as you wish to give it.

This does not limit any non-waivable rights you have as a consumer.

​

5.5 Changes to price or plans

The stores display the price. If a price or plan changes, Apple or Google will handle notice and consent as their rules require. If you do not accept a new price, cancel before renewal.

​

6. Intellectual property

tDo, including software, design, logos, and documentation, is owned by us or our licensors and is protected by copyright and other IP laws. We grant you a personal, non-exclusive, non-transferable licence to use tDo on devices you own or control, via the official stores, for your own use.

You may not copy, reverse engineer, republish, or rent the app except as allowed by mandatory law (for example interoperability).

Open-source components keep their own licences.

​

7. Privacy

Personal data is processed as described in the Privacy Policy. That policy forms part of the agreement for cloud features.

​

8. Third-party services

Ads, store billing, subscription status, and AI inference are provided by third parties listed in the Privacy Policy. Their outages or policy changes can affect those parts of tDo. We are not able to control every ad that a network serves. If an ad is illegal or inappropriate, you can report it through the ad UI where available, or email us.

​

9. Illegal content (Digital Services Act)

When you share a list, we host User Content on our server at your request. We have no general obligation to monitor that content.

Restrictions: no illegal content, including but not limited to child sexual abuse material, incitement to violence or hatred, terrorist content, or clear intellectual-property infringement.

How we moderate: we act when we actually know of illegal content, including after a notice. We may remove or disable the hosted list or share link, lock the PIN, or disable an anonymous account. We do not use automated filters that scan every task title.

Notice and action: anyone may report allegedly illegal hosted content by email to office@xinger.org (subject: tDo illegal content). Please include:

• a link, share code, or other location of the content if you have it

• why you believe it is illegal

• your contact email

• a statement that the notice is accurate to the best of your knowledge

We will assess valid notices in a timely, non-arbitrary way and tell the notifier what we did, as far as the law requires. If we remove content, we will inform the user who hosted it when we can identify them and when the law allows.

Point of contact for users and authorities for these Terms: the contact details in section 17.

We are established in Austria. We have not appointed a separate DSA legal representative in another Member State.

​

10. Disclaimer of warranties

tDo is provided as is and as available. We take care to keep the app useful and the server reasonably secure, but we do not warrant that:

• cloud sync will be continuous or error-free

• AI output will be accurate

• the app will be compatible with every device and OS version forever

• shared content cannot be accessed by someone who obtained the code and PIN

To the extent mandatory consumer law requires it, we remain responsible for conformity of the digital service with the contract.

​

11. Liability

Nothing in these Terms limits liability for intent, gross negligence, injury to life, body or health, or liability under the Austrian Product Liability Act (PHG), or any liability that cannot be limited by law.

For consumers in the EU/EEA, your mandatory statutory rights remain unaffected, including rights under the Consumer Protection Act (KSchG) and rules on digital content and services.

Subject to the two paragraphs above, we are not liable for:

• loss of data that you could have avoided by keeping a copy on the device or by not relying solely on a shared list

• conflicts caused by last-write-wins sync

• misuse of a code and PIN you distributed

• indirect or consequential loss (for example lost profit), unless caused by intent or gross negligence

• the content of ads or of lists created by other users

If you use tDo in the course of a business, our liability for slight negligence is excluded except for breach of essential contractual duties, in which case liability is limited to typical, foreseeable damage.

​

12. Indemnity (business users)

If you use tDo for a business, you will indemnify us against claims that arise from your User Content or from your breach of these Terms, unless we caused the claim by intent or gross negligence.

​

13. Suspension and termination

You may stop using tDo at any time (uninstall, stop sharing, cancel Premium in the store).

We may suspend cloud access if you breach these Terms, overload the service, or if we must do so for security or law. We may stop offering tDo or the cloud backend. If we discontinue the cloud, local copies on devices remain yours to keep or delete.

Sections that by nature should survive (IP, liability, governing law, user-content responsibility, illegal-content rules) survive termination.

 

14. Changes to the Terms

We may update these Terms, for example when we add a feature or the law changes. The current version will be published at this URL and dated. For material changes that affect cloud features, the app may require a new acceptance (legal-document version). If you do not agree, stop using the affected features.

Continued use of local-only tDo after a change that we announced in-app or on this page constitutes acceptance of the new Terms, except where mandatory law requires a different mechanism.

​

15. Governing law and venue

These Terms are governed by Austrian law, excluding its conflict-of-law rules and excluding the UN Convention on Contracts for the International Sale of Goods (CISG).

If you are a consumer resident in the EU/EEA/UK, you also keep the mandatory protections of the law of your habitual residence. You may bring proceedings in the courts of that residence. We may bring proceedings against a consumer only in those courts.

If you are not a consumer, the courts of Austria (place of our registered seat) have jurisdiction.

The European Commission’s ODR platform: https://ec.europa.eu/consumers/odr. We are not obliged to use a specific alternative-dispute body. Store purchases are usually disputed with Apple or Google first.

​

16. Miscellaneous

If a provision is invalid, the rest stays in force. A valid provision closest to the economic purpose replaces the invalid one, unless that would be unfair to a consumer.

These Terms are the entire agreement for use of tDo, together with the Privacy Policy, store terms for purchases, and any in-app consent screens.

We may assign this agreement to a successor that takes over tDo. You may not assign it without our consent.

No waiver is implied unless we confirm it in writing (email is enough).
