lexmail End-User License Agreement (EULA)
Effective date: 2026-09-03 · Version 1.0
This agreement is made between you ("User") and the rights holder of the
lexmail software ("Licensor") regarding the download, installation and use
of lexmail (including the desktop app, CLI tools and local service, the
"Software"). By downloading, installing or using the Software you accept
all terms; if you do not agree, stop installation and delete the Software.
1. Nature of the license
1.1 The Software is provided as closed-source commercial software. All
rights (copyright, trademark, trade secret) are reserved by the
Licensor except as expressly granted here.
1.2 Subject to a valid purchased license (as shown in the in-app
License & Subscription page or official receipt), you receive a
non-exclusive, non-transferable, revocable license to install and
run the Software on the permitted number of devices for your own
non-commercial or internal business use.
1.3 Without a purchased license the Software runs in its free feature
scope; that scope is defined and may be adjusted by the Licensor,
but data already stored on your device is never locked or deleted
because of license state.
2. License types and term
2.1 Lifetime license: perpetual use of the purchased major version
from activation, including version updates for the stated window
from purchase (see the purchase page).
2.2 Subscription license: full licensed features and updates during
the subscription period; after expiry paid features step down and
your local data remains accessible through the free features.
2.3 Licenses bind to devices; the number of devices is stated on the
purchase page. You may unbind and move devices yourself in-app.
2.4 Free trial: each device may start one 14-day full-feature trial;
it ends without grace at expiry, paid features step down, and
local data remains accessible through the free features.
3. Restrictions
3.1 Without prior written consent you may not: (a) copy, sell, rent,
sublicense or otherwise redistribute the Software; (b) reverse
engineer, decompile or disassemble it, or attempt to reconstruct
source code (except where law explicitly permits); (c) circumvent
or help circumvent the license validation mechanism; (d) use the
Software to build a competing product or service.
3.2 You may not use the Software to send spam, unlawful content, or
content infringing others' rights.
4. Privacy and data
4.1 The Software is local-first: mail data, archives and indexes stay
on your device; AI features connect only to model endpoints you
configure yourself by default.
4.2 License validation collects and transmits only the minimum needed
for activation (device fingerprint hash, license key, order id,
version) — never mail contents, credentials or address books.
4.3 See the website Privacy Policy for details.
5. Payment and refunds
5.1 License fees are collected via Lemon Squeezy (international
merchant of record) or other officially designated channels; the
seller of record is shown at checkout.
5.2 Refunds follow the website Refund Policy; mandatory law prevails.
6. Disclaimer and limitation of liability
6.1 The Software is provided "as is", without warranties of
merchantability, fitness for a particular purpose or
non-infringement.
6.2 To the maximum extent permitted by law the Licensor is not liable
for indirect, incidental, special or punitive damages, and total
liability is capped at the amount you actually paid for the
license in question.
6.3 You are responsible for safeguarding your mail credentials and
backing up your local data.
