Terms of service

1. The service

The sender uploads files and creates a link and an 8-character code to give to the people receiving them. You can send without signing in, and recipients get the files through the link or the code without an account.

The service is operated by the person or company named as the operator above.

2. Accounts

• You can send files without signing in (guest sending). A guest can send up to 2 GB per transfer and 5 transfers a day, and files are kept for 1 day (a one-time transfer that closes after one download is also available). Guests cannot email recipients or set a link password, and only a signed-in account can buy a pass.
• The first time you send without signing in, a guest session is created in this browser and a guest account record is created inside the service. If you sign in later in the same browser, transfers that are still open move to your account. Guest account records are deleted automatically, as described in the privacy policy.
• Signing in unlocks larger transfers, email sending, your sent history and passes. You can sign in with a 6-digit code sent to your email or with a Google account; the first sign-in creates your account.
• Recipients do not need to sign in.
• You are responsible for the email account you sign in with and for your signed-in sessions.
• You can ask us to delete your account at the email shown under "Contact" at the top of this page. Deleting it removes your account (email address) data, except billing records we must keep by law for the periods in the Privacy Policy.

3. Links and recipients

• Anyone who has the link can download the files until the transfer expires or reaches its download limit. The sender decides who gets the link.
• If a link password is set, only people who enter it can download. Link passwords come with a pass.
• The download limit counts "visits that start a download". The first download reduces the remaining count by one, and for the next hour more files from the same browser do not reduce it again.
• "Download all" works only for 10 GB or less in total and 1,000 files or fewer. Above that, files are downloaded one by one.
• Vaslo does not offer end-to-end encryption. For sensitive files, we suggest encrypting them yourself before sending.

4. Retention and deletion

• A transfer expires automatically once the retention period the sender chose has passed, and its files are deleted from storage. The cleanup job runs about every 10 minutes, so there can be a short gap between the expiry time and the actual deletion.
• The sender can delete a transfer at any time. The link closes right away and the files are deleted from storage. A transfer sent without signing in can be deleted from your sent history after you sign in in the same browser, and otherwise it is deleted automatically when its retention period ends.
• An upload that was interrupted and is still not finished after 24 hours is stopped and deleted automatically.
• A download address that was already started before a deletion can keep working for up to 5 minutes.
• Expired or deleted files cannot be recovered. Vaslo has no recovery feature.
• A link that cannot be opened shows the same message whether it never existed, expired, was deleted or was blocked.

What we store and for how long is described in the privacy policy.

5. Limits and passes

The limits for the free plan and each pass are below. These are the values the service actually applies.

• A pass is a one-time purchase. It is not a subscription and does not renew automatically.
• Transfers created while a pass is active get the pass limits. When the pass ends, transfers you already made stay until the retention period you set.
• If you buy another pass, it starts when your current pass ends. If passes overlap, the higher tier's limits apply.
• Payments are handled by Polar as the merchant of record. You enter card details on Polar's checkout page; Vaslo does not receive them.
• If a refund is processed, that pass ends at the time of the refund. Transfers already made stay.

Refunds follow the Refund Policy: a full refund on request within 7 days of payment if you have not used any feature the pass unlocked; otherwise no refund, and the pass stays active until the period you paid for ends. We never refund automatically.

Prices are the amounts shown on the pricing page. Payment is in US dollars, and any tax due in your country is shown at Polar's checkout. We give 30 days' notice of price or limit changes on screen or by email.

6. What you must not do

Do not send files or messages of the kinds below, and do not spread a link for the purposes below.

• Files that are illegal
• Files that infringe other people's rights, such as copyright
• Malicious software (viruses and the like)
• Collecting other people's personal data without a lawful basis, or breaking the law
• Passing on links for spam, fraud or phishing
• Trying to get around the service's limits, rate limits or bot checks, and requests that put excessive load on the service

7. Reports and blocking

• The download page has a "Report a problem" link. Recipients can report without signing in.
• An operator reviews the report and, if needed, blocks the transfer. A blocked link stops opening right away and its files are deleted from storage.
• Records of blocked transfers and of reports are not deleted automatically.
• If we suspect a violation from a report or our own checks, we may block the transfer or restrict the account, and we will tell the sender by email where possible, before or after.
• If a sender disagrees with an action, they can appeal by email within 30 days of the notice. We review the appeal, tell them the result by email, and lift the block if the appeal is justified. Files that were already deleted cannot be recovered, so they may have to be uploaded again.

8. Usage restrictions

• To prevent abuse there are rate limits on requesting sign-in codes, starting a guest session, creating transfers, entering link passwords, starting downloads and sending reports, and some screens run a bot check (Cloudflare Turnstile).
• Email has a daily sending cap. Above the cap the link is still created but the email to recipients may not be sent; the screen tells you when that happens.

9. Changes to the service and the terms

• We may add, change or end features. We give 30 days' notice before material changes that are unfavorable to you.
• If we shut the whole service down, we give 30 days' notice so you can download your files, and we refund the unused part of any pass already paid for.
• The service may be temporarily unavailable for maintenance, incidents or third-party outages; we give advance notice where we can.
• We announce changes to these terms and their effective date on screen 7 days before they take effect (30 days for changes unfavorable to you, which we also send by email). If you do not agree, you can stop using the service and ask us to delete your account before the effective date.
• Contact us at the email shown under "Contact" at the top of this page.

10. Scope of responsibility

• We are not liable for failing to provide the service because of events beyond our control, such as natural disasters, war, power cuts, network failures or outages of third-party services (hosting, payment providers, email delivery).
• We are not liable for damage caused by you, such as poor account security or a breach of these terms.
• We are not liable for the content of the files you send, or for transactions and disputes between senders, recipients or third parties.
• Expired or deleted files cannot be recovered, so we recommend keeping your own copy of important files.
• None of the above limits our liability for damage caused by our intent or negligence, or where the law provides otherwise.

11. Governing law and disputes

These terms are governed by the laws of the Republic of Korea. Disputes are resolved by the court with jurisdiction under the Korean Civil Procedure Act.
