Backups in ChanTan Studio: What's Saved and What Isn't

Your app's data is backed up automatically every day. Here's where to see it, why there's no restore button yet, and the one thing Undo can never bring back.

Two different things get saved in ChanTan Studio, and it matters which is which:

The rest of this page is about the second one.

1. Open "Manage ▾" → "Database"

At the top of your project, press "Manage ▾", then "Database".

2. Open "Safe copies" from the engine room

From "Your app's engine room", tap the "Safe copies" card.

3. Read the list

You'll see your daily copies listed by date: "Your database is backed up automatically" — "Chantan backs up your database every day — you don't need to do anything."

The first backup starts within 24 hours of your database being created.

✅ Done. You should now see a dated list of daily copies. There is nothing to press — the list is there so you can confirm the copies exist.

🔴 There is no restore button

This is the most important thing on this page, and it is worth being blunt about:

⚠️ Nothing in ChanTan Studio lets you press "restore my database" yourself. The backups screen is a read-only list.

If you need data restored, contact support and they perform it for you.

One card in the engine room says backups let you "restore your data from any day" — that wording is wrong. Don't rely on it.

What "Undo" does and does not do

Undo restores your files and code. It never restores your data.

Deleted records are gone. That's exactly why the AI stops and asks you to confirm in the chat before running anything that permanently deletes data — take that prompt seriously and read it before answering.

Same for the "Delete this row permanently?" confirmation on the Database screen, and the delete-typing confirmation when removing one of your app's users.

Restoring your app's code (this one you can do)

Your code is a separate, self-service story:

• Version History — the collapsible bar at the top of the chat panel — lists every build. Click a version to preview it, and use the restore arrow to roll back.
• Undo / Redo sit under the chat input for stepping one version back or forward.
• Versions can be pinned so they're protected from cleanup, renamed, or deleted.

Making your own copy of your data

There's no whole-database export button, but there are two honest options:

Note that "Export data" in Settings → Security is a different thing: it downloads your ChanTan account data (profile, projects list, credit history, preferences), not your app's records or its source code.

Your files

Photos, uploads and documents your app stores live under "Manage ▾" → "Database" → "Engine room" → "Files", split into "Public files", "Private files", "Profile pictures" and "Backups", each badged "Public" or "Private".

Limits worth knowing: 50 MB per file, and share links from "Copy link" are "valid for a short time" — they expire on purpose.

Reassurance about your data

• Running out of credits never deletes your data. If your wallet can't cover a paid database level for a day, the project quietly drops back to Free — "your data is always safe." You're warned first: "Low credits. Top up to keep your database fast — your data is always safe."
• Data protection is on by default. "Chantan turns on data protection for every table when you publish — you don't need to do anything."
• Pausing or unpublishing a site never deletes it. Sites are paused, never removed.
