Privacy Policy

Last updated August 26, 2026

This service is operated by Matis Langsam for his own personal use. It has no customers and collects no data about anyone else.

What is collected

How it is used

Solely to operate the assistant: to understand a request, produce a reply, deliver a scheduled reminder, and recall something the owner asked it to remember. Nothing is used for advertising, profiling, or analytics.

Where it is stored

In a private database on Cloudflare's platform, controlled by the owner. Message content is sent to Anthropic's Claude model for the sole purpose of generating a reply, and to the telephone carrier that delivers the message. No other party receives it.

Sharing

No mobile information is sold, rented, or shared with third parties or affiliates for marketing or promotional purposes. Personal information is not sold or traded under any circumstances. The only disclosures are to the service providers named above, strictly to deliver the service, and to anyone the law compels.

SMS consent

Consent is given by the owner texting the service from his own phone, and applies only to him. SMS consent is never shared with third parties. Consent is withdrawn by replying STOP, which stops all messages.

Retention and deletion

Data is kept only while it is useful to the owner and can be deleted by him at any time. To request deletion, email mat@matlangsam.com.

Security

Connections are encrypted in transit. Access credentials are stored as encrypted secrets, and only the owner can reach the stored data.

Children

The service is not directed to children and no one under 13 uses it.

Changes

Any change to this policy will be posted on this page with a new date above.
