Terms

The terms for using Vesper and Vesper Plus, in plain words.

Last updated 12 November 2026

Who we are

Vesper is a web browser made by Jayden McNab ("we"). By installing or using Vesper you agree to these terms. If you do not agree, do not use it.

Using Vesper

You may install and use Vesper on your own computers. The browser is free. It is built on Chromium and other open source software, which stay under their own licences.

You are responsible for what you do with it. Do not use Vesper, or the services behind it, to break the law, to harm others, or to attack or overload our services or anyone else's.

Accounts

An account is optional. If you make one, keep access to it to yourself and tell us if you think someone else has used it. Your sync passphrase is yours alone: we cannot see it and we cannot reset it. If you lose it, you can start Sync over from a computer that still has your sidebar.

Asking Vesper

Vesper's answers are written by an AI model. They can be wrong, out of date or incomplete. Check anything that matters, and do not rely on an answer as medical, legal or financial advice. Free accounts have a daily limit on answers; we may change that limit.

Vesper Plus

Vesper Plus is a subscription that removes the daily limit on answers. It is billed monthly in advance and renews each month until you cancel. The price is shown on the pricing page and at checkout, where any tax that applies where you live is shown before you pay.

Our order process is conducted by our online reseller Paddle.com. Paddle.com is the Merchant of Record for all our orders. Paddle provides all customer service inquiries and handles returns.

You can cancel at any time from Vesper's settings. After you cancel, Plus stays on until the end of the period you have paid for, and you are not charged again.

Refunds

If Vesper Plus is not for you, ask for a refund within 14 days of a payment and you will get that payment back in full, no reason needed. Write to jayden.devbox@gmail.com from your account's email address, or ask Paddle through the receipt they sent you. Refunds go back to the way you paid.

Changes to the service

Vesper changes often. We may add, change or remove features, and we may change the price of Vesper Plus for future periods; if we do, subscribers are told before their next renewal and can cancel first.

Ending things

You can stop using Vesper and ask us to delete your account at any time. We may suspend or close an account that breaks these terms or abuses the service.

No warranty

Vesper is provided as it is. We work to keep it fast, safe and available, but we do not promise that it will be free of errors or interruptions. To the extent the law allows, we are not liable for indirect or consequential losses from using it, and our total liability to you is limited to what you paid us in the twelve months before the claim. Nothing here takes away rights you have by law as a consumer.
