Share a file with no signup

You came here because the last service you tried wanted a name, an email, a password, and a confirmation click before it would accept your file. sto.care doesn't. Drag a 5 GB file into the box on the homepage, paste the recipient's email, hit send. That's it for you. No verification email arrives in your inbox. There's no dashboard to log into later.

We'll be precise about the "no signup" claim, because plain talk is the whole pitch: the sender never creates an account. The recipient gives nothing either. The only email address that gets collected is the recipient's, and that's because the link is delivered by email rather than copy-paste. If that's a dealbreaker, fair, but it's the trade we make to keep the recipient experience to one click.

Why the signup wall existsWhy most file sharing tools require a signup

Free SaaS in 2026 isn't really free. The unit economics only work if a percentage of free users either upgrade or stay on the marketing list long enough to be sold to advertisers. EFF's 2019 report Behind the One-Way Mirror lays out the mechanics in detail: the advertising industry is the dominant market force behind third-party tracking, and the free tools you sign up for are the collection points. File sharing followed the same playbook.

The signup form is the gate that makes that economy work. Every field on it has a job. Email goes to the lifecycle marketing tool. Name goes into retargeting audiences. The verification click confirms the address is reachable, which raises its market value. By the time you're uploading your file, you've already given the company more than the file is worth to them.

Dropbox is the clearest example. To send a single file with Dropbox Transfer the sender has to be on a Dropbox account, which means going through an account-creation flow before anything else happens. Google Drive needs the whole Google account. WeTransfer's free tier is technically signup-free, but it caps you at 10 transfers a month, which pushes any regular user into making one anyway.

How it worksHow sto.care works without an account

The whole flow takes about ten seconds the first time. Open the homepage. Drop the file into the upload zone, or click and pick it from your machine. Type or paste the recipient's email into the field below. Click send. The browser uploads directly to S3 over TLS, the link gets emailed to the recipient, and you get a confirmation email of your own with a one-click revoke button in case you change your mind.

Nothing in that flow asked who you are. The only data we're holding ten seconds after you hit send is: the file itself (encrypted at rest), the recipient's email, your IP for rate limiting, and a random ID for the link. All of it goes after seven days, or sooner if you click revoke.

What you actually saveWhat "no signup" actually saves you

The obvious thing it saves is two minutes. The less obvious things are bigger. There's no password to forget and reset six months from now when you need to send another file. There's no marketing email landing in your inbox every Tuesday because you signed up once in 2024. There's no "your free trial is ending" nag two weeks later.

And there's a quieter benefit that only matters when it matters: if a service you signed up for once gets breached, your email and password hash are in the dump. Privacy regulators have been pushing a principle called data minimisation for years: the safest data is the data you never collected. Not having a sender account on sto.care means there's no row to leak in the first place.

What you give upWhat you lose by not having an account

Worth being upfront about. You don't get a transfer history, so if you sent a file last Tuesday and want to know whether anyone downloaded it, the only record is the confirmation email we sent you. You can't resend the same link from a dashboard, because there is no dashboard. There are no team or workspace features, no shared folders, no co-editing.

For most senders this is a non-issue. You wanted to send one file to one person. You did. Most people who think they need transfer history actually want a search of their own sent folder, which their email already does. If you genuinely need a dashboard with a list of past transfers and bulk resend, you probably want a paid Dropbox or Google Workspace seat, not us.

How the alternatives compareWhere the "no signup" claim actually holds

We checked. Here's how the most common alternatives stack up on the specific question of whether the sender needs to create something:

The pattern is consistent: the services that don't require a signup find another lever. WeTransfer caps your free transfers. TransferNow pushes you toward an account through a series of upsells and tracker-heavy retargeting (their privacy notice lists Facebook Pixel, Google Ads, and Hotjar with a 36-month retention). Dropbox and Google make the account a hard prerequisite, full stop.

Our lever is different. We auto-delete every file after seven days, which means we don't accumulate the storage cost that forces a freemium funnel in the first place. No long-tail storage means no pressure to monetise the long tail of free users. It's why we can keep this signup-free without a transfer cap or a tracker grid.
