Privacy Policy

Last updated: July 26, 2026

NewsletterScriv is operated by GlyphStack LLC (P.O. Box 494, Benton, PA 17814). Privacy questions and requests: legal@glyphstack.com.

The two kinds of people we hold data about

Authors — our customers, who create accounts. For authors, we decide how account data is handled, and this policy describes it.

Readers— the subscribers on an author’s list. A reader’s data belongs to the author who collected it; we process it only to provide the service, on that author’s instructions. If you’re a reader with a question about a newsletter you’re on, the author is the right first stop — the unsubscribe link in any of their emails works instantly, no login, no questions. We’ll help with anything they can’t resolve.

What we never do

Who helps us run the service

These providers process data on our behalf, under their own contractual commitments:

AI assistance is different, and opt-in. The writing assistant in the campaign editor runs on your ownAPI key, which you add yourself in settings. If you turn it on, the text you ask it to work on is sent to the provider you chose — Anthropic, OpenAI, or Google — under your account with them and their terms, not ours. Add no key and nothing is ever sent. We don’t train models on your content, and we don’t send your subscriber list to any AI provider.

Data is processed in the United States. If you use NewsletterScriv from elsewhere, you understand your data (and your readers’ data) is transferred to and processed in the U.S.

Cookies

We use the session cookies our authentication requires, and your browser’s local storage for preferences like the light/dark theme. No third-party advertising cookies.

Retention

Security

Traffic is encrypted in transit. Credentials are handled by dedicated providers, stored secrets (like API keys you connect) are encrypted at rest, and production access is limited to what operating the service requires. No one can promise perfect security; if a breach affects your data, we’ll tell you promptly and plainly.

Your rights

Children

NewsletterScriv is intended for adults and is not directed at children under 16, and we don’t knowingly collect their data. If you believe a child’s data has reached us, tell us and we’ll remove it.

Changes

If this policy changes in a way that matters, we’ll notify authors by email or in the dashboard before the change takes effect. The “last updated” date above always tells you the current version.
