Terms of Use

What these terms cover#

These terms are the agreement between you and RONE Labs for using Daylum.

They cover the Daylum app for iOS and Android, and this website. Installing the app, opening it, or reading this site means you accept them. If you do not accept them, do not use Daylum, and remove the app from your device.

How Daylum handles your data is a separate document. It is the privacy policy, and nothing on this page overrides it.

Daylum is not medical software#

Daylum is a self-reflection tool. It is not medical software, and it is not a medical device.

It offers no diagnosis, no treatment advice, and no crisis intervention. Nothing it shows you is a clinical assessment, and nothing in it is a substitute for care from a qualified professional.

The moods, activities, streaks, statistics, and reports describe what you recorded yourself. They are a reflection of your own notes, not a measurement of your health, and they are not evidence of a condition or of recovery from one. Do not use Daylum to decide whether to start, stop, or change any treatment.

If you are in crisis, or you think you may be, contact your local emergency number or a crisis line where you live. Daylum cannot reach anyone on your behalf. It has no account, no server, and no way to send a message to anybody.

Your license to use Daylum#

You get a personal, non-transferable license to use Daylum on devices you control.

The license is for personal, non-commercial use. It lasts as long as you follow these terms, and it is a license to use the app rather than a sale of the software itself. RONE Labs keeps ownership of the app, this website, the Daylum name, and the artwork.

What the license does not include:

• Selling, renting, sublicensing, or redistributing the app.
• Copying or reusing the Daylum name or artwork as your own.
• Reverse engineering or decompiling the app, except where local law gives you that right regardless of what an agreement says.

Your journal is not covered by this license, because it is not the developer’s to license. The entries, notes, and photos you write stay yours. Daylum claims no rights over them, and could not exercise any if it did: they stay on your device, so there is nothing to hold a right in.

Daylum Plus, purchases, and refunds#

Daylum is free to download. Daylum Plus is one optional one-time purchase, and Apple or Google processes it.

There is no subscription and no Daylum account. The payment happens in the App Store or Google Play sheet, under that store’s own payment terms. Daylum receives only the result: an entitlement saying this device owns Plus.

Refunds are handled by the store that took the payment. The developer never receives your payment and cannot issue, approve, or reverse a store refund. Apple documents its process at Apple Support, and Google at Google Play Help. Each store decides under its own policy.

Plus is tied to your store account, not to your journal. Restoring it asks the App Store or Google Play whether that account owns the product, so a restore works on a new device signed in to the same store account and does not work on a different one. There is no Daylum server to ask instead.

Plus never gates your data. Exporting a backup, importing one, exporting a CSV copy, and deleting everything are free, and they stay free. What Daylum Plus unlocks is described in the app, and what it means for your data is in the privacy policy.

Your backups are yours to keep#

A backup you export is your file, in your custody, from the moment it leaves the app.

Daylum can create a backup and restore one. It cannot see where you put the file afterwards, cannot retrieve it, cannot protect it, and cannot delete it for you. There is no copy anywhere else, so if you lose the file, the data in it is gone.

Keeping a backup is worth doing, and keeping it somewhere you trust is your call. Uninstalling Daylum removes its storage on the device. Without a backup you saved beforehand, there is nothing to restore from, and the developer has nothing to restore it from either.

A password-protected backup cannot be recovered without its password. The password is never stored and never leaves your device, so a lost password means an unreadable file. What a backup contains is described in the privacy policy.

Acceptable use#

Use Daylum lawfully, and do not attack it or the people around it.

Concretely: do not use the app or this website to break the law, do not try to interfere with or gain unauthorized access to either, do not misuse someone else’s device or copy of the app, and do not attempt to defeat a purchase or distribute a modified build. Daylum has no accounts, no shared content, and no comments, so there is no public surface here to moderate and no other user for you to reach.

If you break these terms, the license in them ends. There is no account to suspend, so that is the only consequence there is.

Provided as is, with no warranty#

Daylum is provided as is, with no warranty, to the extent local law allows.

The app is built and maintained by one developer. It is not promised to be uninterrupted, error free, or fit for any particular purpose, and no promise is made that it will always be available, always be compatible with a future version of your operating system, or preserve data through a device failure.

Limitation of liability. To the extent local law allows, the developer is not liable for indirect or consequential loss, or for lost data, arising from your use of Daylum. Where liability cannot be excluded, it is limited to the amount you paid for the app, which for most readers is nothing.

Some places give consumers rights that an agreement cannot remove. Nothing on this page takes away a right you have under the law where you live, and where a clause here conflicts with one of those rights, the law wins.

The store’s own terms still apply#

The store you installed Daylum from has its own terms, and they still apply.

On the App Store, Apple’s standard licensed application end user license agreement applies to the app unless a custom agreement is supplied in its place. No custom agreement is supplied, so Apple’s standard one governs the license Apple grants you. This page does not replace it, and where the two differ on something Apple’s agreement covers, Apple’s agreement is the one that governs.

On Google Play, the Google Play Terms of Service apply to your download and to any purchase you make there.

Both stores also handle the payment for Daylum Plus, so the store’s terms rather than these govern billing and refunds.

Governing law#

Not yet decided. This section is a placeholder.

The governing law for these terms, and the courts that would hear a dispute about them, are not settled yet. No country, state, or court is named here until they are, and the date at the top of this page moves when the full clause replaces this one.

Nothing on this page chooses a jurisdiction or asks you to agree to one. The consumer law where you live applies to you exactly as it otherwise would.

If you need to know which law applies before you rely on these terms, write to ronelabs26@gmail.com and you will get the current answer rather than a guess.

Changes to these terms#

The effective date and last-updated date at the top of this page are the record.

These terms can change when the app changes. If they do, the dates above move and the change is listed below. Continuing to use Daylum after a change means the updated terms apply to you, because there is no account through which you could be asked separately.

Contact#

Questions about these terms go to ronelabs26@gmail.com.

It is a real mailbox read by the developer, and it is the only contact route there is. RONE Labs is the publisher named on both store listings.

If your question is about using the app rather than about these terms, the support page answers the common ones, including how to export a backup, restore one, restore a purchase, and delete everything.
