Terms of use

Version 3 - 7 October 2026

These terms of use (the "Terms") govern the use of the Blautime application (the "Application") and of the purchases related to it. The Application is published by Alexandre Thil (the "Publisher" or "we"). "You" means the person who installs or uses the Application (the "User"). Only the French version of the Terms is binding; this English text is an automatic translation made with artificial intelligence, provided for convenience only, and may contain errors.

Read this first. The Application is provided as is, with no guarantee that it works or of any result. Your data stays on your device: the Publisher does not hold it and cannot recover it, and only you can protect it with regular backups (section 7). Sections 10 to 13 limit the Publisher's liability; if you are a consumer, your mandatory legal rights remain intact.

1. Acceptance of the Terms

When the Application shows you the Terms and asks you to accept them, this express acceptance is required to use it. Any use of the Application, including before that acceptance, is subject to the Terms, which can be read at any time from the Application and on the Publisher's website. If you do not accept the Terms, you must not use the Application.

You declare that you have the legal capacity to enter into this agreement. If you are under 18, you declare that you act with the consent of your legal representative. The Application is not intended for children under 16. If you use the Application on behalf of a company or another legal entity, you declare that you are authorised to bind it; it is then bound by the Terms as you are, and the provisions that apply to professional users apply.

2. Nature and description of the Application

The Application is a tool that calculates times useful for photography; it does not take photos. For the place and the date you choose, it shows the times of the blue hour and the golden hour, sunrise and sunset, the moon and the direction of the sun. It works without an account with the Publisher: your data are stored on your device, and the Publisher has no access to them.

It must not be used as the only means of proof, nor for decisions on which the safety, health or rights of people depend.

Features may change. We may add, change or remove features, in particular to take account of technical change, security, the law or the rules of the application stores, while respecting the rights you have under the law as a consumer. Features marked as new, experimental or in testing may be changed or removed at any time.

A device may not receive updates if its hardware is not, or no longer, compatible, or if it does not have enough free storage space. Some features may not work on every device. Some features need an Internet connection (for example advertising, store purchases, downloads or synchronisation); the charges of your Internet access provider or mobile operator may apply.

3. Licence

Subject to compliance with the Terms, the Publisher grants you a personal, non-exclusive, non-transferable and non-sublicensable licence to use the Application, in object code form, on the devices you own or control, for your own needs, including in the course of your own professional activity. The licence is granted for as long as you use the Application in compliance with the Terms. The terms of use of the store from which you obtained the Application also apply.

When the Application is obtained from the App Store, the licence is also governed by Apple's standard licence terms for applications; Apple is not a party to the Terms, is not responsible for the Application or its content and has no obligation to maintain or support it.

4. Restrictions

Except in the cases and within the limits expressly permitted by law, in particular by article L. 122-6-1 of the French Intellectual Property Code, you agree not to:

• Copy, modify, translate, adapt, decompile, disassemble or attempt to reconstruct the source code of the Application;
• Circumvent or disable the trial, subscription, licence or security mechanisms of the Application;
• Sell, rent, lend, distribute, sublicense or make the Application available to third parties;
• Remove or alter the intellectual property notices of the Application;
• Use the Application for unlawful or fraudulent purposes or against the rights of third parties, in particular by recording or sharing third parties' personal data in it without a legal basis;
• Disrupt the operation of the Application or of the services it uses.

5. Intellectual property

The Application, its name, code, interface, texts, visuals and logos are the property of the Publisher and are protected by intellectual property law. The licence does not transfer any ownership right to you. The data you enter in the Application remain yours.

6. Price, trial and subscription

The Application can be downloaded and used free of charge, with ads. The end of a trial or of a subscription does not, on our part, delete the data stored on your device.

The free version of the Application shows advertising provided by third-party advertising networks, in particular Google AdMob. The Publisher neither chooses nor controls the content of these ads and is not responsible for the products or services they promote; following an ad takes you to a third party, under its own terms. The data processing related to advertising, and your choices about it, are described in the privacy policy.

7. Your data: only you hold and back them up

The data you enter (settings) are stored only on your device and in the copies you choose to make. The Publisher does not host them, has no access to them, is neither their depositary nor their custodian, and has no obligation to keep, back up, restore or return them. It cannot view them or recover them for you, even at your request.

You alone are responsible for your data, their accuracy, their keeping and their backup. Regular backups are the only effective protection against their loss. In particular, it is up to you:

• To make regular backups, using the backup and export means offered by the Application or by your device, and to keep them on a medium or service separate from your device;
• To check regularly that your backups are recent, complete and readable, in particular before changing phone, uninstalling the Application, resetting your device, updating its system or the Application, enabling or changing a synchronisation, or restoring a backup;
• To keep by your own means any document or information you are required to keep;

You acknowledge that no guarantee is given against the loss, alteration, duplication or unavailability of data, which may result in particular from:

• The loss, theft, failure or breakage of your device, or a failure of its storage;
• Uninstalling the Application, clearing its data, resetting the device or changing phone;
• Updates of the operating system, the device or the Application, or a defect of the Application, which backups are precisely meant to make up for;
• The operation of third-party storage and backup services (for example cloud storage or your device's system backup, whose space may be limited, beyond which the backup may no longer be made);
• Restore operations, which replace the data on the device with the content of the restored backup;
• Malware, a wrong action, your own choices (in particular a confirmed deletion) or the action of a third party.

The absence of sufficient backups, or failing to check your backups, is a fault on your part that excludes or, at the very least, reduces the Publisher's liability to the extent that it caused or worsened the damage, under the conditions of section 11. The cost and time needed to re-enter or rebuild data remain your responsibility.

8. Not applicable to this application

9. Third-party services

Some features rely on services provided by third parties, in particular your device's operating system, the application stores, storage and backup services (for example Google Drive, Dropbox, Android or iCloud backup) and, depending on the Application, calendars, advertising networks or the online services it connects to. These services are subject to their own terms and privacy policies, are beyond the Publisher's control and may be changed, interrupted or withdrawn at any time by their providers. Synchronisation also depends on the permissions granted, the device settings (in particular battery saving) and the network connection; delays, duplicates, conflicts or deletions may occur.

The Publisher does not guarantee the availability, operation or compatibility of these services and is not liable for their acts, their failures or their consequences on your data. You remain solely responsible for the calendars you choose to sync or share, for the choices you make when the Application asks you (in particular before a deletion), and for the people you share your calendars with.

10. Application provided as is, with no guarantee that it works

To the fullest extent permitted by law, the Application is provided "as is" and "as available", without any warranty of any kind, express or implied, beyond the mandatory legal guarantees recalled below. In particular, the Publisher does not guarantee that the Application meets your needs or any particular purpose, that it works without interruption, failure, error or defect, that it is compatible with every device, system version and configuration, that its results are accurate or suited to your situation, or that your data are kept.

The Publisher is bound by a mere obligation of means (best efforts). It provides no service level, no minimum availability, no correction time and no permanent support: it endeavours to fix the defects reported to it, in the order of priority it decides, and support is provided by email, as far as reasonable and without any guaranteed time. Some updates may be required to keep using the Application; the Publisher may stop supporting older versions of the Application, of operating systems or of devices. It is up to you to check, in particular during the free trial, that the Application works on your device and suits your use.

If you act for professional purposes, and to the fullest extent permitted by law, any warranty other than those expressly provided in the Terms is excluded, in particular any warranty of fitness for a particular purpose, of result, of availability or of data retention.

If you are a consumer, you benefit in all cases from the legal guarantee of conformity applicable to digital content and services (articles L. 224-25-12 and following of the French Consumer Code), including for the updates needed to keep the Application in conformity, and from any other mandatory legal guarantee. Nothing in the Terms limits them.

11. Liability

The Publisher is liable only for direct, certain and foreseeable damage resulting from a proven breach of its obligations attributable to it alone. Its liability cannot be incurred, and is excluded or reduced proportionately, when the damage results in whole or in part from:

• Your own act, in particular the absence of backups or checks (section 7), not checking the results produced by the Application (section 8 where applicable), use contrary to the Terms or to the documentation, or your settings and synchronisation choices;
• Your device, its operating system, its configuration or your network connection;
• The act of a third party, or the operation of the third-party services mentioned in section 9;
• A case of force majeure within the meaning of section 13.

If you act for professional purposes, and to the fullest extent permitted by law:

• The Publisher is not liable for any indirect or consequential damage, in particular the loss or alteration of data, the cost of rebuilding them, loss of turnover, profit, customers, pay, time or opportunity, damage to reputation, back-pay claims, reassessments, penalties or sanctions, or claims by third parties;
• The Publisher's total liability, for all causes and all damage combined, is limited to the lower of the following two amounts: the sums actually paid to use the Application during the twelve months preceding the event giving rise to the damage, or one hundred euros (€100);
• Any action against the Publisher must, on pain of being time-barred, be brought within one year of the event giving rise to it, in accordance with article 2254 of the French Civil Code.

These limitations are an essential part of the balance of the Terms and of the price of the Application, free or paid. Nothing in the Terms excludes or limits the Publisher's liability for gross negligence or intentional misconduct (fraud), for death or personal injury, or in the other cases where the law prohibits such an exclusion or limitation. If you are a consumer, the Terms do not deprive you of the rights you have under the mandatory provisions of consumer law, in particular your right to compensation if the Publisher fails to meet its obligations.

12. Indemnity by professional users

If you act for professional purposes, you shall indemnify the Publisher against any claim, action, judgment, sanction or expense (including reasonable defence costs) brought against it by a third party, in particular your employer, your employees, your clients or an authority, and arising from your use of the Application, from the data you record or share in it, from the documents you produce with it, or from a breach by you of the Terms or of the law.

13. Force majeure

The Publisher is not liable for any delay or failure to perform resulting from a case of force majeure within the meaning of article 1218 of the French Civil Code. The following in particular are considered as such, where they are beyond its control: the failure or interruption of networks, hosting, storage or calendar services or application stores, a change in their rules or technical interfaces, an operating system update making the Application incompatible, a cyberattack, a decision of a public authority, a natural disaster, a fire, a flood, an epidemic or a general power failure.

14. Term, suspension and termination

The Terms apply as long as you use the Application. You may stop using it at any time by uninstalling it, after backing up your data; the subscription is cancelled separately, from the store (section 6).

In the event of a serious breach of the Terms (in particular fraud, circumvention of the licence mechanisms or unlawful use), the Publisher may suspend or terminate the licence, after informing you where possible, without prejudice to the rights you have under the law. The Publisher may also stop distributing or maintaining the Application, giving you reasonable notice; subscriptions then stop renewing, and you keep, for the period already paid, the rights the law grants you. In all cases, the data stored on your device and your backups remain available to you; it is up to you to export them. Sections 7, 8, 10, 11, 12, 13, 17 and 18 survive the end of the Terms.

15. Changes to the Terms

The Publisher may change the Terms, in particular to follow changes in the Application, the law or the store rules. Each version has a number and a date. A material change is notified to you in the Application or on the website before it takes effect, with reasonable notice; the Application may ask you to accept the new version. If you refuse it, you may stop using the Application and cancel your subscription from the store. Otherwise, continuing to use the Application after the new version takes effect constitutes acceptance.

16. Personal data

The processing of personal data by the Application and the website is described in the privacy policy.

17. General provisions

The Terms, together with the privacy policy and the terms of the application store, form the entire agreement between you and the Publisher on their subject. If a provision of the Terms is held void or unenforceable, it is deemed unwritten, or reduced to the maximum extent allowed by law, and the other provisions remain in force. The Publisher's failure to rely on a breach does not waive its right to rely on it later. The Publisher may transfer the Terms to a third party taking over the operation of the Application, provided that the transfer does not reduce your rights; you may not transfer your rights and obligations without the Publisher's consent.

The electronic records of the Application and of the stores (in particular the acceptance of the Terms, purchases and settings) are binding between the parties, unless proven otherwise, and may be produced as evidence.

18. Governing law and disputes

The Terms are governed by French law. If you are a consumer residing in another Member State of the European Union, you keep the protection of the mandatory provisions of the law of your country of residence.

In case of difficulty, please write to us first so that an amicable solution can be sought. If you are a consumer and your written complaint to the Publisher has not been resolved, you may use a consumer mediator free of charge, in accordance with articles L. 612-1 and following of the French Consumer Code; the mediator's contact details are given on request and shown in the Application as soon as one is appointed.

Failing agreement, the dispute is brought before the competent courts. If you are a consumer, you may bring proceedings, at your choice, before the court of the place where you lived when the contract was concluded or when the harmful event occurred, or before any other court competent under the law. If you act for professional purposes, exclusive jurisdiction is given to the courts of the Publisher's place of business, including in the event of several defendants or third-party proceedings.
