Privacy & Data

Privacy notice

This page describes how No Noise Letter handles your data right now, during early access. It is intentionally specific to the product as it exists today: approved-access accounts, necessary auth/session storage, transactional email, and no optional analytics or marketing cookies at this stage.

Effective date: 2026-04-02

1. Controller and contact

Controller: No Noise Letter (operated by Kuba Szwajka)

Product: No Noise Letter — an AI-assisted personal newsletter and editorial briefing service.

Support: support@nonoiseletter.com

2. What personal data we process now

account and identity data such as your email address, Clerk identifier, and optional name
newsletter workspace data such as newsletter names, schedules, topics, and generated editions
delivery records such as recipient email, provider message ID, send status, and delivery errors
generation metadata such as prompts, search queries, source URLs, and model and debug traces stored with editions
basic technical and security data such as request logs and session/auth state

3. Why we process it

We currently process personal data to:

provide access to the app and authenticate approved users;
sync and maintain a local user record linked to the authenticated account;
store newsletters, topics, generated editions, and delivery history;
send necessary service emails and edition deliveries;
operate, secure, debug, and improve the service during early access.

4. Processors and infrastructure

Provider	Role
Clerk	Authentication, account identity, email verification, and session handling.
Resend	Transactional email delivery.
OpenRouter	Model gateway used for AI-assisted generation.
Tavily	Web research for gathering source material.
Langfuse (optional)	AI telemetry and debugging traces when explicitly enabled in server config.
Railway	Application hosting.

5. Cookies, local storage, and tracking

Right now we store only the necessary auth and session data. No optional analytics or marketing cookies are intentionally loaded at this stage.

Clerk auth/session cookies

Required to sign users in, keep sessions active, and protect authenticated routes.

Necessary

Browser localStorage key `i18nextLng`

Stores the selected interface language (English or Polish).

Necessary for language preference

Optional Langfuse telemetry

Only used when Langfuse keys are configured on the server to inspect AI generation traces.

Server-side only

6. Retention

We keep account, newsletter, topic, edition, and delivery records while the account and service are still active, and for as long as they are needed to operate, secure, and troubleshoot the service.

Some operational records may persist longer in backups, logs, or provider systems. The product does not yet offer self-serve deletion or export, so retention is intentionally conservative for now and will tighten before any public launch.

7. Your choices and rights

You can contact us to request access, correction, deletion, or clarification about the personal data we hold during early access.

If you are in the EU/EEA, you may also have the right to object to some processing or to lodge a complaint with your local supervisory authority. For users in Poland, that includes the President of the Personal Data Protection Office (UODO).

8. Early-access note

This privacy notice is deliberately narrow. It reflects the product as it exists today in early access: no public signup, no paid subscriptions, no marketing consent flow, and no optional analytics by default. If the product expands, this page will expand with it.
