Terms of Use
Effective: August 4, 2026 - Version history
  1. What these terms are

    These terms of use ("terms") are an agreement between you and the operator of I Know My Time ("application", "service", "we"), a web application operated from the European Union that shows you where your Google Calendar time goes and what it is worth. The application is available worldwide. After you sign in for the first time, the application asks you to confirm these terms before you can use it, and records which version you confirmed and when; that confirmation is what makes this agreement binding between us. If you do not agree with them, do not confirm and do not use the application. How we handle your data is described separately in our Privacy Policy, which forms part of this agreement.

  2. Your account

    You sign in with your Google Account. You may only use an account you are entitled to use, and you are responsible for the activity that happens under it. You must be at least 16 years old and legally able to enter into this agreement.

  3. Calendar access is read-only

    The application asks for read-only access to your Google Calendar. It cannot create, change, or delete anything in your calendar. You can revoke the application's access at any time in your Google Account permissions; the application will simply stop working until you grant access again.

  4. Exports write to your Google Drive

    If you use the export feature, the application additionally asks for Google Drive access limited to files it creates itself. With it, the application creates an "I Know My Time" folder in your Drive and saves your export files there. It cannot see, change, or delete any other file in your Drive. This is the only place where the application writes anything into your Google Account; the export files are yours and stay in your Drive. Exports are optional — if you do not use them, this access is never requested.

  5. What we store

    Your calendar data never passes through our systems: your browser reads it straight from Google and analyses it there, and we keep no copy of it. What we do store is your account identifiers, your settings (for example saved filters, currency, and preferences), and a record of the choices you make here — such as accepting these terms or opting out of our e-mails. Everything is processed in line with the EU General Data Protection Regulation (GDPR); the Privacy Policy lists it in detail, including our commitment to the Google API Limited Use requirements. You can delete your account and this stored data yourself at any time in the application settings.

  6. The service is free (for now)

    The application is currently provided free of charge, with no obligation on your side. We may introduce paid features later. If we do, we promise three things: paid features will be clearly marked as such; nothing will ever start charging you without you actively choosing and confirming a purchase; and if a feature you already use moves behind payment, we will tell you in advance, give you a transition period during which it stays free for you, and you may end this agreement instead — with the option to export your data first.

  7. Fair use

    Use the application only in a lawful way and only for its purpose: analyzing calendars you have legitimate access to. You must not attempt to disrupt or overload the service, gain access to other users' data, or use automated tools to scrape or abuse it. We may suspend or terminate accounts that violate these rules.

  8. Who owns what

    The application itself — its software, design, texts, and name — belongs to us and is protected by copyright and trademark law. While these terms are in force you get a personal, non-exclusive, non-transferable licence to use the application as it is offered, for your own purposes. You may not copy, resell, or sublicense it, and you may not decompile or reverse-engineer it beyond what the law expressly allows you regardless of any agreement.

    Your data stays yours. Your calendar remains yours and Google's business; the settings you create here and any file you export to your Google Drive are yours, and we claim no rights over them beyond running the application for you.

  9. E-mails from us

    As our user you may occasionally receive product news from us (new features, tips & tricks) in accordance with the EU rules on electronic mail to existing customers (Article 13(2) of the ePrivacy Directive 2002/58/EC and its national implementations). You can refuse these e-mails when you first sign in, any time in the application settings, or via the unsubscribe link included in every such e-mail. Service messages — for example a notice that these terms changed — are not marketing and may be sent to you regardless of this preference.

  10. Ending the agreement

    You can stop using the application at any time and delete your account and stored data in the application settings — no notice, no reason needed.

    We may suspend or terminate your access if you materially breach these terms. Where reasonable we will warn you first, we will tell you why, and you can ask us to reconsider through the contact form; if the reason falls away, we restore the account. We may also discontinue the service altogether. In that case we will announce it at least 30 days in advance on the application website and by e-mail, so that you have time to export your data before it shuts down.

  11. No warranty, limited liability

    The application is provided "as is" and free of charge. We do our best to keep it available and correct, but we do not guarantee uninterrupted availability or that the insights are error-free — they are only as good as the data in your calendar. The application is an analytics tool; its outputs are not tax, accounting, or legal advice, and decisions you base on them are yours.

    To the extent the law allows, we are not liable for indirect or consequential damage, lost profit, lost savings, or for loss of data caused by Google's services or your own device — nor for the consequences of your using the application in breach of these terms.

    What we never exclude: liability for damage caused intentionally or by gross negligence, liability for harm to life or health, and any rights the law gives you as a consumer that cannot be limited by agreement. If any limitation above goes further than your law permits, it applies only as far as that law allows and the rest stays in force.

  12. Changes to these terms

    We may change these terms to a reasonable extent (for example when the application gains new features or the law changes), as permitted by applicable law. When we do, we will publish the new version here with a new effective date, keep the previous versions in the history below, and ask you to confirm the new version in the application on your next sign-in. If you do not agree with a change, you can end the agreement immediately by deleting your account in the application settings.

  13. Governing law and your consumer rights

    These terms are governed by the law of the Czech Republic, the country the service is operated from, excluding its conflict-of-law rules. If you are a consumer, this choice never takes away the protections granted to you by the mandatory rules of the country where you live, and you may bring disputes before the courts of that country. Out-of- court settlement of consumer disputes in the operator's country is handled by the Czech Trade Inspection Authority — adr.coi.cz (coi.cz). Consumers elsewhere in the EU can find their national dispute-resolution body through the European Commission's consumer redress portal.

    We offer the service from the European Union and build it around EU rules. We do not tailor it to the laws of other countries, so if you use it from outside the EU, you do so on your own initiative — which does not take away any mandatory protection your local law gives you.

  14. The small print

    If any provision of these terms turns out to be invalid or unenforceable, the rest stays in force and the invalid part is replaced by the closest valid rule. Not enforcing a right straight away is not a waiver of it. We may transfer this agreement to another party — typically if the service changes hands — provided your rights are not reduced; you will be told in advance and may end the agreement if you do not want to continue with them. You may not transfer your account to someone else. Neither side is liable for a delay or failure caused by events outside its reasonable control, such as outages of Google's services or of the internet infrastructure. Together with the Privacy Policy these terms form the whole agreement between us about the application and replace any earlier arrangement. They are written and binding in English; any translation is provided for convenience only.
