Privacy policy

1. Who we are

Mel is an agentic terminal product operated by Concepts Dzign LLC. Website: https://www.openmel.dev/. Contact for privacy requests: hello@openmel.dev.

2. Information we collect

We may collect information you voluntarily provide, including:

• Name, email address, company name
• Mobile phone number (when you opt in to SMS)
• Message content and support request details
• Account information used to create a Mel account
• Consent records (timestamp, source page, disclosure version, opt-in method)

When you use the Mel AI agent, your prompt, the files it reads and the output of the commands it runs are sent to the Mel relay, which calls model providers on your behalf. Hosted-plan keys are held server-side; your own key is stored on your device and sent with each request. Conversations are stored on your device, and a copy syncs to your Mel account unless you turn that off in Settings → Privacy. Memory notes that Mel saves are stored on Mel's server; memory is on by default and you can turn it off.

We may also collect limited technical information such as IP address, browser type, page URL, and timestamps for security, fraud prevention, rate limiting and abuse prevention, consent recordkeeping, and counting downloads. Our download service keeps a log of each download and each app update check, which includes the IP address and the browser or app type; it is deleted after 30 days and read only to count downloads.

3. How we use information

We use collected information to:

• Provide, maintain, and improve Mel products and services
• Create and manage Mel accounts
• Respond to contact, sales, and support requests
• Send service, account, and support communications you request
• Send SMS messages only when you provide the applicable SMS consent
• Comply with legal, regulatory, and carrier messaging requirements

4. Mel product / AI agent data handling

The Mel terminal runs locally. It sends nothing you type or run unless you use the AI agent, or AI command suggestions (Settings ▸ AI, on by default): when local autocomplete has nothing, suggestions send the line you are typing, your current folder and your last eight commands to the Mel relay. Turn the setting off and nothing you type in the terminal leaves your machine. If you pair a phone, see Mel Remote below.

When you use the Mel AI agent, selected context is forwarded to the Mel relay and may be processed by one or more model providers (for example Anthropic, OpenAI, Google, Groq, DeepSeek, and Moonshot, and other providers shown in the app's model picker). Each provider's privacy policy governs how they handle data sent to their APIs.

Mel Remote (your phone or iPad). If you pair a phone or iPad with Mel on your computer, the phone can show your open conversations and recent messages, let you allow or deny some of Mel's requests, stop a run and send Mel a message. What passes between your computer and your phone is encrypted on one and decrypted on the other, with a key your computer makes and passes to your phone in the QR code. That key never reaches Mel's servers, so our servers only carry messages they cannot read. Mel does see that a phone is paired to your account, its type (iPhone, iPad or Android), and roughly when it connects. The encrypted messages are deleted after 24 hours (queued commands after 10 minutes, a pairing code after 10 minutes). Removal from storage can take up to two more days. Unpairing a phone, or deleting your data, removes all of it from our systems. Backups hold the same unreadable messages, and the record of which phone is paired to your account. They expire within 5 weeks. While a phone is paired, Mel on your computer contacts our servers about every 2 seconds while the phone is open and about every 15 seconds otherwise. If you do not pair a phone, it sends nothing for this feature, except one check, when you open the Phone page in Settings, of whether a phone is paired (no content).

5. SMS / text messaging privacy notice

If you opt in to receive SMS messages from Mel / Concepts Dzign LLC, we collect your mobile phone number and SMS consent status so we can send the messages you requested.

A. Informational and customer-care messaging

Mel / Concepts Dzign LLC may send informational and service-related SMS to customers and prospective customers who requested contact and consented to receive text messages. Message types may include:

• lead follow-up after an inquiry or demo request
• consultation or demo scheduling
• onboarding coordination
• account-related communication
• customer care and service follow-up

B. Required messaging disclosures

• Message frequency varies
• Message and data rates may apply
• You can opt out at any time by replying STOP
• For help, reply HELP or email hello@openmel.dev
• SMS consent is optional and is not required to download Mel, create an account, purchase Mel services, or complete a transaction

C. Mobile number non-sharing statement

We do not share, sell, or provide your mobile phone number or messaging consent data to third parties or affiliates for marketing or promotional purposes.

Mobile opt-in data is not sold to lead generators and is not shared as a shared/purchased list. Authorized service providers (such as Twilio) may process messaging data only as needed to deliver messages and maintain compliance records on our behalf; they are not authorized to use your mobile opt-in data for their own marketing.

D. Separate consents

Informational and service-related SMS consent is separate from any marketing or promotional SMS consent. We do not treat support or follow-up consent as marketing consent.

6. Information sharing

We do not sell your personal information.

We may share information only:

• With service providers who help operate our website, infrastructure, forms, or messaging (under confidentiality / data-processing terms)
• When required by law or to protect rights, safety, or security
• With your direction or explicit consent

Mobile phone numbers and SMS consent are not shared or sold for third-party marketing or promotional purposes.

7. Cookies and analytics

This website does not use tracking cookies for advertising. Signing in to your Mel account on this website sets a session cookie used solely to keep you signed in. When configured, the website uses Sentry for error reporting; this is not used for advertising or cross-site tracking. To count page visits and see which sites send visitors to us, the website uses Vercel Web Analytics, which sets no cookies, does not track you across sites, and does not store your IP address or any other personal data.

Crash reporting in the Mel desktop app

Released builds of the Mel desktop app report crashes to Sentry so we can tell whether a release is stable before it reaches everyone. A report contains only the crash message and the line of Mel’s own source code it came from, the Mel version and update channel, your operating system, processor architecture, and which graphics renderer was in use. It also sends a start-and-stop signal per app session, with no content, so we can measure what fraction of sessions crashed.

It does not send your terminal output, commands, prompts, files, file paths, conversations, API keys, email address, IP-derived location, or machine name, and it attaches no memory dumps. Crash text is filtered for anything key-shaped or address-shaped before it leaves your machine. You can turn crash reporting off entirely by setting the environment variable MEL_SENTRY=0; development builds never report at all.

8. Data retention and deletion

Newsletter and account email addresses are held until you unsubscribe or request removal. SMS consent and related records may be retained as needed for compliance, opt-out suppression, and legal obligations. To request deletion or access, email hello@openmel.dev.

Backups are kept in the United States and in the European Union (Ireland). When you delete your account, it leaves our backups within 5 weeks.

9. Your choices

• Unsubscribe from email newsletters via the email unsubscribe link or by contacting us
• Opt out of SMS by replying STOP
• Request help for SMS by replying HELP
• Request access, correction, or deletion by emailing hello@openmel.dev

10. Changes

We may update this Privacy Policy from time to time. Updates will be posted on this page with a revised effective date.
