FAQ

You can sign in with Google, or sign up / sign in with your email (signing up only needs an email and a password). After signing up with email, tap the link in the verification email before you start; the first time you sign in, you'll set your name and 24h ID. Phone number sign-in is coming soon.

Check your spam folder first, and add the sender noreply@use24h.com to your contacts so future emails don't get blocked. Still nothing? On the "Verify Your Email" page, tap "Resend Verification Email" (once every 60 seconds), then tap the link in the newest email.

On the sign-in page, choose "Sign in with email" → "Forgot password". Enter your email and we'll send you a link to reset your password.

Your 24h ID can't be changed once it's set, so double-check before you save it. You can change your name, photo, and status anytime from "Edit Profile" at the top right of "Me" (or "Me › Personal info").

Me → Account Security → Delete account. Your data is deleted along with it and can't be recovered; subgroups you created are handed over to the main group's creator. Photos and videos you uploaded to one-on-one and group albums are permanently deleted 90 days after you delete your account. During those 90 days they stay in the album, and the uploader is shown as "Deleted user". If you want to keep them, download them before you delete your account.

Sign in on your new phone with the same Google account or email. Your data is stored in the cloud and syncs back automatically. You can sign out of your old phone from "Signed-in Devices".

Tap the add friend icon at the top right of the Friends tab. You can search by 24h ID, scan a QR code, or share your QR code or 24h ID with them.

In the Pending inbox or at the top of the chat, you can choose "Agree & add friend" or "Block". They won't be notified when you block them, and you can unblock them later in "Me › Privacy & Permissions › Blocked List".

The request is hidden, and the other person won't know. It only shows up again if they send another request. To remove the request, tap "Decline".

Tap the create group icon (the two-people icon) at the top right of the Chats tab. Once the group is created, you can share an invite link starting with use24h.com/join; a group can have up to 1,000 people. In the group, open the menu at the top right → "Manage Group" → "Create Subgroup". A subgroup can be set to "Public" or "Approval Required".

For a subgroup that requires approval, main group members can only see its name. They need to send a request, and the subgroup's creator has to approve it before they can join. Until then, they can't see anything inside.

Go to the subgroup → Manage Subgroups → "Transfer Subgroup Ownership". You can choose a subgroup member or the main group's creator. Before the creator can leave a subgroup, they also need to pick someone to take over.

The main group's creator can tap "Freeze Project" on the Manage Group page. The main group and all its subgroups become read-only, and members' chats move to the archive automatically, where they can still be viewed and searched. The group can be unfrozen later.

Tap the archive icon at the top right of the Chats tab. Archiving only affects you. Archived chats don't jump back to the list when new messages arrive, and you can unarchive them anytime.

Yes. You can unsend messages you sent within the last 24 hours, including text, photos, voice messages, and cards: long-press the message → "Unsend Message" → "Unsend". Once unsent, nobody can see it, and it can't be restored. Unsending a poll card or sign-up card marks it as canceled; unsending an event or ledger card doesn't delete the event or the ledger entry.

When adding an event, choose friends or groups under "Invite". Once they accept, the event shows up on both calendars. You can also see your "Shared Calendar" on a friend's profile page.

Yes: Calendar → Settings → Import Calendar → Link Google Calendar, or import an .ics file. Only you can see the details of events imported from Google; friends just see that time as "Busy".

Priority: P0 is the most urgent (red), P1 is important (orange), and P2 is normal (gray, the default). Tap the tag to change it; choose "Urgent" under the calendar to sort by priority.

Yes. When adding an event or to-do, turn on the "URL" switch and enter it. If it doesn't start with http, https:// is added automatically. Tap the link to open it in your browser.

Add an entry in the chat's Shared Ledger or a Project Ledger, then choose who paid and who's splitting it (split equally, custom amounts, or by ratio). The Settle Up page works out the fewest transfers needed. If an entry is wrong, the person who added it can open it and tap "Edit".

When adding an entry to a Project Ledger, choose the currency and enter the exchange rate yourself (you can check your bank's posted rates). Next time, the last rate you used for that currency is filled in automatically. Later changes in the exchange rate don't affect entries you've already added.

Project Ledgers are open to everyone with no limit, on both the free plan and Pro.

On the Settle Up page, tap "Mark as Paid" on that transfer. Either the payer or the receiver can tap it, and whoever tapped it by mistake can undo it.

No. 24h only records and calculates; it never handles any money. Please pay each other by bank transfer or cash.

No. Your diary, weight, period records, Personal Ledger, and the Assistant's Stash (called "My Note" when the Assistant is turned off) are visible only to you. Today's Mood is also only visible to you by default; after you share it with specific people, they'll see a Mood Bubble on your profile photo, which disappears automatically at 23:59 that day.

Me → Close Ones, then invite them. Once they accept, you can keep track of anniversaries, answer a daily question, share a Wish Box, and write letters to the future together. The free plan allows up to 5 Close Ones; Pro has no limit.

Planned 24h Pro pricing: NT$125 per month or NT$1,190 per year, with the first month free. These are planned prices and Pro isn't available to buy yet. You can tap "Notify Me When Available" on the 24h Pro page.

Yes, every feature is free to use. The only differences between Pro and the free plan are: storage (1GB / 10GB), AI chats (30 / 600 per month), Close Ones (up to 5 / no limit), and ads (yes / no).

Only you can read and write your private data, which is protected by the database's security rules. Your birthday and social links are visible only to friends. You can also export your data from "Me › Account Security › Export my data".

24h will never ask you for your password, verification code, or money. A stranger asking you to invest, send money, or buy gift cards or points is most likely a scam. Please block them right away.

These count toward your storage: photos, videos, and voice recordings saved to an album, diary photos, anniversary photos, event and to-do attachments, files in the Assistant's Stash, and photos, videos, and recordings in Moments. These don't count: photos, videos, and voice messages sent directly in chats (they expire after 7 days). Each file is stored only once and counted only once. The free plan has 1GB and Pro has 10GB. Going over the limit doesn't delete any files; you just can't upload more until you delete old files or check out 24h Pro.

Photos, videos, files, and voice messages sent directly in chats expire after 7 days. To keep one, long-press the message and choose "Save to Album", or tap "Save to Album" under the photo. Once saved to an album, it's kept forever and counts toward the storage of the person who saved it.

Photos are compressed automatically (about 2,000 pixels on the long side). Turn on "Send photos in HD" in Me → Chat for clearer photos, or tap the ⊕ on the right of the input bar and choose "File" to send the original. You can pick up to 9 at a time. Each video can be up to 5 minutes, voice messages up to 5 minutes, and chat files up to 50MB. Events and to-dos can have up to 3 attachments of 10MB each; diaries can have up to 5 photos a day; each Moments post can have up to 9 photos or videos plus one recording of up to 60 seconds.

Each message you send to the Assistant and its reply counts as 1. Reading a photo, summarizing long text, or reading a link counts as 3 (you'll be told before it's used). Each live translation counts as 1. These don't count: Draw a Card and Fortune, Stash, browsing albums, Quick Log (the shortcut chips above the input box and the ⊕ feature panel), voice-to-text, and sentences the Assistant understands directly, like "weight 58" or "lunch 120". The free plan has 30 per month and Pro has 600. They reset on the 1st of each month and don't roll over.

When you've used up this month's chats, you can still log your weight, expenses, and mood with "Add Entry" and "Today's Mood" above the input box, or with "Quick Log" in the ⊕ on the right of the input bar, and you can keep using Draw a Card and Stash. Your chats reset automatically on the 1st of next month.

Only the free plan shows native ads, on a few low-sensitivity pages (such as the bottom of the ledger stats page, below the calendar, and on Draw a Card results). Pro and the free trial never show ads. Ads never appear in chats, Assistant chats, diaries, Period, mood, Close Ones, Moments, or albums, and your health, period, mood, and diary data is never used for ads.

Planned prices, not available to buy yet. Extra storage (Pro only): +100GB NT$150/month, +500GB NT$590/month, +1TB NT$1,190/month. Extra AI chats: +500 chats NT$59/month, +2,000 chats NT$199/month.

Pro gift cards are coming (Pro for 3 months, Pro for 1 year). Buy one for a friend or one of your Close Ones, and they tap "Claim" to activate it; if they already have Pro, the days are added to the end. Not available yet; prices will be announced at launch.

In your diary, pick "Today's Mood" and tap "Share", then choose Close Ones or friends (you can pick more than one). You can add a short message of up to 20 characters. They'll see a Mood Bubble on your profile photo and can tap "Hug" or "Cheer", or open a chat. The bubble disappears automatically at 23:59 that day, and you can cancel it anytime. They can't see your diary, your other moods, or your period data.

Moments are updates from your friends. On the Friends tab, tap "Moments" next to the title at the top, and post from the top right. You can post text, photos, videos, and a recording (up to 9 photos or videos per post, recordings up to 60 seconds), and choose whether all friends, only your Close Ones, or specific friends can see it.
