Frequently asked questions
Answers to the most common questions about pricing, data, accounts, and supported platforms.
About pricing
Can I use niyase for free?
Yes. The FREE plan lets you use all desktop and mobile features entirely locally. Only if you need cloud sync or sharing across multiple devices should you consider the PRO plan (¥780 / space / month) or higher.
What are the differences between plans?
| Plan | Monthly | API limit | Storage |
|---|---|---|---|
| FREE | ¥0 | — | Local only |
| PRO | ¥780 / space | 100,000 calls / mo | 1GB |
| PREMIUM | ¥2,980 / space | 500,000 calls / mo | 5GB |
For details, see Pricing plans.
What happens if I exceed the API limit?
There is no metered billing. Responses gradually slow down (throttling), so it is designed so that your operations do not stop.
What is the billing unit?
Per space. The number of accounts and members is free and unlimited.
About the interface
The app's look has changed. I can't find the old menu
We redesigned the interface in July 2026. The top horizontal app bar has been replaced with a rail-style sidebar (two columns: one rail for choosing a category, the other for that category's items). Mobile follows the same idea with a persistent header and a shelf (a two-level drawer) instead of the app bar. See How navigation works for details.
I can't find the invite button
The member-invitation entry point moved from a permanent rail icon to the meta menu (⚙) → Access management → Members tab. You can also search for "invite" in the command palette to jump straight there. See Members for details.
How do I make someone else the owner?
Owners can no longer be added by invitation. Invite your successor as a member first, and once they've joined, use the ownership transfer flow to hand over the owner role. See Members for details.
Notifications aren't arriving, or they're in the wrong language
Notifications arrive through three channels: the in-app bell, email, and push. A notification's content is stored as a locale-independent fact and rendered in each recipient's own language setting when displayed, so the same notification can appear in different languages for different members. If notifications aren't arriving, check whether the relevant category is turned off in your notification settings. See Notifications for details.
Are backups taken automatically?
Not by default. Each space can opt in to "daily automatic backup" (off by default). Once enabled, you can view and restore daily backup history from Space settings → Backup. Manual export / import is also available separately. See Backup and restore for details.
There's no in-app tour or walkthrough
That's intentional. Guidance on how to use the app now comes from three sources: (1) persistent, always-visible affordances such as empty-state prompts and the command palette, (2) the first-run welcome guide, and (3) this documentation site. If you're looking for how to do something, start with the relevant page on this site (such as How navigation works).
About data
Where is my data stored?
- Desktop / mobile: encrypted SQLite on the device
- Cloud: a tenant-isolated DB on Google Cloud (Tokyo region)
Can I use it offline?
Desktop and mobile work fully offline with all features. The cloud version (browser) requires being online.
Can I back up my data?
Yes. For details, see Backup and restore.
What happens to my data if I close my account?
It is physically deleted after a 30-day soft-delete period. It can be recovered within that period.
What if I want to erase my data completely?
niyase organizes data ownership into three layers: "space," "account," and "device." Choose the procedure that fits your goal.
- Want to erase only a specific space → Space settings → Data management tab → "Erase everything" (erases the entire DB of that space)
- Want to clean up login history on this device → Avatar menu → "Manage account"
- Want to erase all of niyase from this device (transfer / sale / disposal) → see the per-platform steps below
- Web (cloud.niyase.com): the browser's "Delete all site data," or delete the browser profile
- iOS / Android: uninstall the app (the OS erases it automatically)
- macOS: uninstall the app + delete
~/Library/Application Support/niyase/ - Windows: uninstall the app + delete
%APPDATA%/niyase/
- Want to reliably make the entire device clean → we recommend deleting the OS user / a factory reset. This also clears traces such as browser cache and OS indexes all at once. In MDM environments, follow your IT department's procedures
niyase does not provide bulk operations above the space level (such as resetting the entire device). It is designed so that data ownership layers are clearly separated as "space = niyase" and "device = OS," with each managing only its own abstraction. When you want to reliably make a device clean for transfer or disposal, combine this with OS-level operations.
About accounts
Is account registration required?
It is not required for offline use on desktop / mobile. Cloud sync and multi-device use require signing up.
Can I use multiple accounts on one device?
One device = one local profile. You cannot use multiple accounts locally at the same time. With the cloud version (browser), you can switch using separate browser profiles.
I forgot my password
You can send a reset email from "Forgot your password?" on the login screen. If you have registered a passkey, recover using passkey authentication.
About platforms
Which OSes are supported?
- Desktop: macOS (Intel / Apple Silicon) / Windows 10 or later
- Mobile: iOS 16+ / Android 10+
- Cloud: the latest versions of Chrome / Edge / Safari / Firefox
Can sole proprietors use it?
Yes. It can be used regardless of size or industry. For sole proprietors there is also a personal space (up to one per account).
