Privacy Policy

Langladder rewrites the webpages you already read into your target language at your chosen level. This policy explains what we collect, why, and the choices you have. We try to collect as little as possible.

What we collect

• Account information. When you create an account we store your email address and name, and a securely hashed password. If you sign in through a third-party account, we receive basic profile information (such as your name, email, and avatar) from that provider instead of a password.
• Page text you choose to translate. When you translate a page, the visible text on that page is sent to our servers and to our AI provider to produce the rewrite. We use it only to generate that translation and do not store the page contents afterward.
• Words you save. Vocabulary you save for review — the word, its definition, the surrounding sentence, and the target language and level — is stored in your account so you can review it later. When you save from the Chrome extension, the source page URL is also stored with the card.
• Operational data. We keep limited request metadata (such as counts used to enforce rate limits) needed to run the service reliably and prevent abuse.
• Web app analytics and diagnostics. On the Langladder website and web app, PostHog collects a pseudonymous account identifier, basic browser and device information, coarse product actions (such as creating a deck or rating a review), technical error details, page URLs, referring pages, and marketing parameters used for traffic attribution. Account-recovery tokens, card-search terms, and tag names in URLs are masked. This tracking is not included in the Chrome extension. On the public homepage and non-authentication onboarding screens, PostHog also collects heatmaps and session recordings to help us improve those pages. Form inputs are masked, and recording is disabled on authentication and authenticated app pages.

How we use your information

• To translate and define the pages and words you ask us to.
• To store and schedule the vocabulary you save for review.
• To authenticate you and keep you signed in across the web app and the browser extension.
• To send transactional email such as address verification and password resets.
• To understand whether core learning features are useful, improve the product, secure the service, prevent abuse, and fix problems.

We do not sell your personal information, and we do not use your saved words or browsing to serve advertising.

Service providers

We rely on a small number of providers to operate Langladder, who handle data only to provide their service to us:

• AI language-model providers — generate translations and definitions from the text you submit.
• Cloud infrastructure and email providers — hosting, database, and email delivery.
• Identity providers — only if you choose to sign in with a third-party account.
• PostHog — provides product analytics and browser error monitoring for the Langladder website and web app. PostHog is not embedded in the Chrome extension.

The Chrome extension

The Chrome extension does not contain PostHog or any other analytics tracker. It does not send your browsing history, visited URLs, or page content to an analytics service, and we do not use it to monitor or build a record of your browsing activity.

The extension receives temporary access to the active page only after you ask it to simplify or translate the page, define text, or save a learning card. It sends only the text needed to perform the action you requested. If you choose to save a word or sentence, its source page URL is stored with that card in your account; this is part of the saved learning item, not analytics tracking. The extension does not request Chrome's browsing history permission or ongoing access to every website. It stores a session token locally so it can talk to your account; signing out of the extension clears it.

Data retention & your choices

We keep your account and saved words until you delete them or close your account. You can delete saved cards from the web app at any time. To delete your account or request a copy of your data, email us at the address below.

Security

Data is encrypted in transit, passwords are hashed, and every request is scoped to the signed-in account so your data is only ever accessible to you. No method of storage or transmission is perfectly secure, but we work to protect your information.

Children

Langladder is not directed to children under 13, and we do not knowingly collect personal information from them.

Changes to this policy

We may update this policy from time to time. When we do, we will revise the “Last updated” date above, and significant changes will be communicated where appropriate.
