How to reach the developer#

Write to ronelabs26@gmail.com. It is a real mailbox, read by the developer who makes Daylum.

There is one person behind the app, so a reply may take a few days. It is not an automated inbox and nothing you write there is public.

What helps a reply arrive faster: your device and operating system version, the Daylum version from More, then About, what you expected to happen, and what happened instead. Daylum has no account and keeps no record of you anywhere, so nothing about your situation is already known here.

Never send your journal, a backup file, or screenshots of entries you would not want read. None of it is needed to answer a support question, and email is not private storage.

Export a backup#

A backup is a single file containing your whole journal, including your photos. Making one is free and takes a few taps.

1. Open the More tab, at the end of the bottom bar.
2. Scroll to the Data section and tap Export backup.
3. Choose a backup type. Standard is the free one. Encrypted protects the file with a password you set, and is part of Daylum Plus.
4. Tap Export, then pick the folder to save into when your device asks. On Android that is the system file picker, on iOS it is the Files sheet.

The saved file is named daylum-backup followed by the date and time, ending in .zip for a standard backup or .daylumenc for an encrypted one. Daylum confirms the size when it is written.

The folder you pick is on your device or in whichever storage app you chose from that picker. Daylum uploads nothing: it hands the file to your operating system and stops there. Where it goes next is up to you.

Restore a backup#

Restoring reads a backup file you saved earlier and writes it back into the app. It checks the file before it changes anything.

1. Open the More tab, then the Data section, and tap Import backup.
2. Pick your backup file when your device asks for one.
3. If the file is encrypted, type its password at Enter password. A wrong password changes nothing.
4. Read the preview. Restore this backup? tells you how many records the file holds and when it was exported.
5. Choose what happens to data already in the app, then tap Restore.

The two choices under If data already exists:

• Merge keeps what is in the app and adds or updates from the backup. This is the safe default.
• Replace everything erases what is in the app first, then restores only the backup. Use it when the backup is the version you want to keep.

Restoring is always free, including restoring an encrypted backup without Daylum Plus. If the file is damaged, the wrong format, or made by a newer version of Daylum, the app says so and leaves your current data untouched.

Export a readable copy#

A readable copy is a spreadsheet or a document you can open anywhere. It is a different thing from a backup.

1. Open the More tab, then the Data section, and tap Export readable copy.
2. Choose a format, then tap Export and pick where to save it.

The formats:

• CSV is one row per entry with readable columns (date, time, mood, activities, note, photo file names) and no internal ids. It is free, and it stays free.
• Spreadsheet is the same content as a styled workbook for Excel, Numbers, or LibreOffice. Part of Daylum Plus.
• PDF is a readable journal document grouped by day. Part of Daylum Plus.

A readable copy cannot be imported back into Daylum. Only a backup file can be restored, so keep a backup as well if you want to be able to return your journal to the app.

Automatic backups#

Daylum Plus can write a backup to a folder you choose, on a daily schedule, without you opening the app.

1. Open the More tab, then the Data section, and tap Automatic backups.
2. Tap Choose folder and pick where the files should go.
3. Turn on Automatic daily backup. Tap Back up now whenever you want one immediately.

Daylum keeps the three most recent automatic backups in that folder and removes older ones, so it does not grow without limit. Automatic files are named daylum-auto-backup followed by a timestamp, which keeps them separate from the backups you export by hand, and those are never deleted by this.

The operating system decides when background work actually runs, so daily is the earliest cadence rather than a guarantee. The folder is on your device or in a storage app you picked, never on a Daylum server, because there is none. If Daylum loses access to the folder, or the device runs out of space, the status on that screen says so.

Delete everything#

Delete everything erases your journal on this device and resets the app to its defaults. It is immediate and it cannot be undone.

1. Export a backup first if there is any chance you will want the data back. Nobody can recover it for you afterwards.
2. Open the More tab, then the Data section, and tap Delete everything.
3. Type DELETE in the confirmation box, then tap Delete everything.

It erases every entry, note, photo, and customization, then returns the app to first-run setup, the same state it was in when you installed it. Uninstalling Daylum removes its storage as well. There is no server copy to ask about, which is why there is no form to fill in and no waiting period.

Two things it does not reach. Backups you already exported are ordinary files outside the app, so deleting them is up to you. And a Daylum Plus purchase is held by your store account rather than by the app, so a reset does not revoke it: use Restore purchase to get it back. What deletion covers is stated in full in the privacy policy.

Restore a Daylum Plus purchase#

A purchase belongs to your App Store or Google Play account, so a new device, a reinstall, or a reset never loses it.

1. Sign in to the device with the same store account you bought Daylum Plus with.
2. Open the More tab and tap Daylum Plus at the top.
3. Under Already purchased Daylum Plus? tap Restore purchase.

Daylum asks the store whether that account owns the product and unlocks the extras when the store says yes. It does not contact a Daylum server, because there is not one. If nothing changes, the store account signed in on the device is usually a different one from the account that paid.

Refunds are handled by the store that took the payment, and the developer cannot issue one. Apple documents its process at Apple Support, and Google at Google Play Help.

Report a bug#

Bug reports go to ronelabs26@gmail.com, the same mailbox as everything else. There is no public bug tracker to post in.

The app can write the message for you, which saves you retyping the version numbers:

1. Open the More tab, scroll to About, and tap Feedback and support.
2. Tap Report a bug. Your mail app opens with the message ready. Nothing is sent until you send it.
3. Leave Include device details on if you can. It attaches your Daylum version, platform, language, and theme, which is usually what a diagnosis needs.

The device details block contains nothing from your journal, and you can read every character of it on screen before you send. Daylum sends nothing on its own: the app hands your mail app a draft, and you decide whether it leaves.

What Daylum cannot do#

Some things Daylum genuinely cannot do. Each one is the cost of having no account and no server.

• No cloud sync. Your journal does not sync between your phone and your tablet, and there is no website where you can read it. Moving to a new device means exporting a backup and restoring it there.
• No recovery after uninstall without a backup. Uninstalling removes the app’s storage, and there is no copy anywhere else. The developer cannot restore it, because the developer never had it.
• No cross-account restore of Daylum Plus. The purchase belongs to the store account that bought it. It cannot be moved to a different Apple Account or Google Account, and it does not carry across from iOS to Android, because each store sold its own product.
• No password recovery for an encrypted backup. The password is never stored and never leaves your device. A forgotten password means an unreadable file, permanently.
• No refunds from the developer. Only the store that took the payment can issue one.
• No PIN recovery for the app lock. If you turn the app lock on and forget your PIN, and biometrics are not available to you, the only way back in is to reinstall the app, which permanently erases your journal. Daylum keeps no copy of the PIN to check against, so nobody can recover it, including the developer.
• No account recovery, because there is no account. There is no login, no password reset, and no email to send one to.

Daylum is also not medical software. It offers no diagnosis, no treatment advice, and no crisis intervention, and it cannot contact anyone on your behalf. If you are in crisis, use your local emergency number or a crisis line where you live.

Privacy and data questions#

Questions about what Daylum stores, sends, or deletes are answered in the privacy policy.

• Where your journal is kept, and what leaves the device
• What Daylum collects, and what it does not
• Which permissions the app asks for, and why
• What a backup file contains once it leaves the app
• What deleting your data reaches, and what it does not

Anything the policy does not answer goes to ronelabs26@gmail.com, and the answer arrives from the developer rather than from a support desk.
