Frequently asked questions

The Free plan gives you one Ukebaco link and up to 5 files a month. Receiving, sorting into per-client folders, tidy file names, the ledger, Japanese/English upload pages and previews are all included.

The upload page shows "Powered by Ukebaco". No ads are shown.

New submissions are no longer accepted, and the upload page says "Files cannot be accepted right now. Please contact the recipient." As you approach the limit, the dashboard warns you with "N left", which is the moment to consider changing plans. Files already received are not affected.

On the 1st of every month (UTC).

500 MB on Free, 2 GB on Pro and Team. The dashboard's usage card shows it too, for when a client asks.

Pro (¥2,200 / month (tax incl.)): 500 files a month, 2 GB per file, unlimited Ukebaco links, sender email verification and receipt emails (optional), PIN and deadline (optional), and no "Powered by" line.

Team (¥5,800 / month (tax incl.), coming soon): 5,000 files a month (fair use), shared drives, custom logo, and notification on receipt (coming soon).

As a launch offer, anyone who starts Pro before the deadline pays ¥1,100 (tax incl.) a month for the first 3 months. From month 4 the regular price of ¥2,200 / month (tax incl.) applies. We email you before the regular price kicks in. Cancel at any time and nothing further is charged.

Cancellation takes effect at the end of the period you have already paid for. Until then you keep Pro, and the screen shows "Scheduled to cancel on <date>". After that the account becomes Free automatically. To undo, use "Manage payment and cancellation".

The account is treated as Free from that moment (limits return to Free values, and links are paused as described under "What happens to my links when I downgrade?"). Stripe retries the payment for a few days; once it succeeds, the plan and the paused links come back automatically. Files already received are not affected.

Update your payment method under "Manage payment and cancellation". Stripe emails a receipt for each payment.

Prices are set in Japanese yen, but if you sign up from outside Japan, the checkout page (Stripe) offers your local currency. Stripe handles the conversion; its conversion fee (2 to 4%) is included in the converted price. You can also choose to pay in yen.

Local-currency payment works with cards, Link, Apple Pay and Google Pay. Paid plans are not offered to individual customers in the EU or the UK.

Your links remain, but the following are paused automatically.

• Links that use a PIN, a deadline or email verification (so that they are never left open without their protection; we do not strip the settings and keep the link public)
• Of the remaining active links, everything except the 1 most recently created (the Free limit)
• Paused links do not accept submissions, and the distributed URL shows "This link is not available". Trying to resume one prompts you to change plans
• When you move back up, these links resume automatically (links you paused yourself stay paused). Received files and the ledger stay in your Google Drive™
• Before cancelling, "Plan and billing" shows how many links would be affected. When the change is applied, we also email you the list of paused links

Directly in the folder of your Google Drive™ that you chose for the link. Ukebaco's servers never store file contents (uploads go from the browser straight to Google Drive™).

Submission metadata (the fields entered, file names, receipt number, destination) is kept and deleted automatically after 90 days. The ledger lives in a spreadsheet in your Google Drive™, so your own records survive after Ukebaco's copy is gone.

No. Files and the ledger are in your Google Drive™. Only Ukebaco's own records go away.

Only the permission that covers "files this app created and folders you picked" (drive.file). It cannot read the rest of your Drive.

No. They open the link, choose files and send.

To prevent impersonation. So that senders can check who is collecting, the creator's email address is always shown and cannot be hidden. The page also carries a notice not to enter passwords or card numbers, and a link to report abuse.

No. The confirmation step says so explicitly and asks for consent. If something needs fixing, ask the sender to submit again.

On links with email verification, the address is used only to send the verification code, to record it in the ledger and, if enabled, to send the receipt email. Senders see this purpose before entering their address. Ukebaco's records are deleted after 90 days.

Through a channel other than the Ukebaco link URL (phone, chat, and so on). Putting it in the same email defeats the purpose. PINs are 4 to 8 digits.

It stops accepting submissions at the end of that day, and the upload page says "Submissions have closed". The dashboard shows it as expired; pause or delete it to free up the slot.

The upload page for that link stops working and the distributed URL becomes unusable. Received files and the ledger stay in your Google Drive™. If you only want to stop temporarily, use "Pause" (the URL stays the same and "Resume" brings it back).

If the connection drops mid-upload, it resumes from where it stopped on the same page. Closing or reloading the page starts over, so ask senders to keep the tab open while uploading.

Names are built from the field values you picked for folder sorting and file names, using the rules below. Whatever a sender types, files never land outside the folder you chose.

• Path separators (/ \), control characters such as line breaks, and characters Windows rejects (: * ? " < > |) become _. Leading and trailing spaces and dots are removed
• Single-line fields (text, email, phone, choice) accept up to 100 characters and are used as folder names as they are. Long text fields contain line breaks, so they cannot be picked for folders or file names
• In file names, a field value contributes its first 40 characters and the original file name its first 40, so that the whole name including the timestamp stays within 100 characters. The extension is kept
• An empty value skips that level and the file is saved one folder up
• Google Drive™ itself has no length limit, but if you sync to a Windows PC, paths longer than about 260 characters may fail to open. Keep the hierarchy shallow

The dashboard supports WebMCP, a browser mechanism that lets a page hand its actions to the AI agent in the browser as tools. Open the dashboard in a supporting browser and ask the agent for "a Ukebaco link to collect this month's invoices": it asks what it needs, creates the link and returns the URL. You can also ask things like "has Acme sent their invoice?" to check what has arrived.

This is a beta. WebMCP is a new browser capability; as of September 2026 it works in the following environments.

Using it directly from the claude.ai or ChatGPT chat window (remote MCP) is in preparation.

• The built-in browser of the ChatGPT™ desktop app: open the dashboard and talk to the agent (verified)
• Chrome™ 149 and later: experimental (origin trial). Enable chrome://flags/#enable-webmcp-testing to use it from in-browser agents such as Gemini™ in Chrome
• Other browsers and agents as they adopt WebMCP

It can list, create, stop and resume Ukebaco links, and search submissions (what submitters typed, the folder, the reference number and file names). The agent works inside the dashboard you are signed in to, so there are no new permissions or passwords to hand over.

Plan limits and paid features (PIN, deadline, email verification) apply exactly as they do to you. The agent cannot pick an existing folder; files go into a folder the app creates. It never reads file contents.
