What the extension does not send to Dyslexly

Dyslexly is designed to keep reading activity on your device. The extension:

• Does not send webpage text or document content to Dyslexly's servers unless you use the optional Pro "Make easier" tool on selected text (see below).
• Does not send your locally stored reading statistics to Dyslexly.
• Does not sell personal data or use it for advertising.
• Does not require an account for the free reading controls.

What is stored locally

Your settings (font preferences, spacing, overlay colour, etc.) are stored using Chrome's built-in chrome.storage.sync API. This syncs your settings across your devices using your Google account — exactly like Chrome bookmarks. This data is managed by Google and subject to their privacy policy.

Reading stats (pages viewed with Dyslexly active, words spoken by TTS) are stored locally using chrome.storage.local and never leave your device.

Anonymous product telemetry

The extension sends a small number of product events to Dyslexly so we can measure whether onboarding works, understand which optional upgrade route is useful, and investigate removals. These events can contain:

• A randomly-generated installation ID. It is not used for advertising or cross-site tracking. If you start a Pro trial, it is associated with the email you deliberately provide so we can enforce the seven-day trial, send its dates and restore access. If you open Stripe checkout from the extension, the ID is attached to that checkout so we can measure whether onboarding leads to a trial or purchase.
• The extension version number
• Chrome's installation classification (for example, a normal install or an administrator-managed install) and whether the user is allowed to remove it
• The Chrome interface language (for example, en-GB or ro) so aggregate language support can be improved
• An event name such as install, onboarding opened, first meaningful use, upgrade clicked, referral shared, uninstall, or a fixed tool name such as read_aloud or make_easier. Tool-use events never contain what you read, typed or selected.
• A once-per-day active signal when Dyslexly applies a reading setting or you open its popup, used to calculate aggregate daily, weekly and monthly active-user totals
• On uninstall, how long that installation was kept and the extension version

We use your IP address only to determine an approximate network country (e.g. "United Kingdom") so we can understand where Dyslexly is being used. This may reflect a school or company proxy or a VPN rather than the user's physical location. The full IP address is never stored. Active signals and onboarding events do not include the page you were viewing. No webpage text, document content, browsing history or website hostname is included in these events.

Optional onboarding answer and Pro trial email

After you have used Dyslexly, the extension may ask what brought you to it. Answering is optional and the onboarding question does not ask for an email address.

Starting a 7-day Pro trial in the extension or Workspace requires an email but no card. We store the email, any installation ID supplied by the extension, and the trial start/end time to provide and limit the trial, send transactional trial dates and reminders, and restore access on another device. Workspace also keeps the trial email and end time in that browser until you disconnect Pro or clear its site data. The separate marketing checkbox is optional and unchecked by default. Tips and offers are sent only if you tick that box. You can unsubscribe at dyslexly.com/unsubscribe.

Tools that contact other services

Some tools work by opening or contacting a third-party service only when you choose to use them. For example, dictionary lookup sends the selected word to DictionaryAPI and Translate opens Google Translate. Those services process the submitted word or text under their own privacy policies. The Pro assistant tools are described separately below. Core font, spacing, overlay, line-focus and local text-to-speech controls do not require those services.

Make easier, Explain and Fix writing (Pro or trial only)

If you use Make easier, Explain, or AI-backed grammar correction in the extension or Workspace, Dyslexly sends only the passage you deliberately selected to dyslexly.com. Dyslexly passes that selection to Anthropic to generate the requested result. Dyslexly does not write the selected text or generated result to its database or application logs; Anthropic processes the request under its own applicable service terms and privacy commitments. We store only a daily usage count against your licence or trial email so we can apply a fair usage cap. Listen-aloud uses voices already on the device and does not send page text. Free reading tools never send page text.

If you use Suggest a feature, we send your suggestion (and optional email) to our team inbox. We do not publish suggestions.

Licence key validation

If you purchase a Pro licence, the extension or Workspace sends an API request to dyslexly.com/api/validate-licence containing only your licence key. No browsing data, personal information, or page content is included. The extension caches the result for 24 hours. If you connect Pro in Workspace, the key is stored in that browser until you disconnect it.

Website (dyslexly.com)

When you visit dyslexly.com:

• We use Google Analytics 4 to understand traffic and improve the site (anonymous usage statistics).
• Anonymous extension product events may be sent to GA4 with the event name, extension version, Chrome interface language, installation classification and approximate network country — no page content.
• If you make a purchase, your email and payment data are processed by Stripe under their privacy policy.
• Licence emails are stored to send keys and receipts. A Pro-trial email is required only when you choose to start Pro in the extension or Workspace and is used for trial access, restore and transactional messages. We do not add you to marketing lists without your separate consent.

Dyslexly Workspace

Dyslexly Workspace processes pasted text, text-based PDFs, Word documents and images in your browser. Opening and reading a document does not upload its contents or extracted text to Dyslexly's servers. If you deliberately use a Pro assistant tool, only the selected passage is sent as described above. Readings you deliberately save, your current draft and your reading preferences are stored in that browser's local storage and can be removed from the Workspace.

Image text recognition uses Tesseract.js on your device. The first use downloads the OCR engine and selected language model from the library's content delivery service; the image itself is not sent with that download. Workspace records fixed, content-free analytics events such as opening a document, starting a trial, completing a Pro action or selecting the Pro link. A random Workspace ID and the first Dyslexly page that led you there can be used to join those steps to checkout and payment so we can measure which routes work. The ID is not used for advertising or cross-site tracking. These events never contain the filename, document text, image or extracted words; the trial email is stored separately for access as described above.

Data retention

Licence records are retained for the duration of your subscription plus 90 days for dispute resolution, then deleted.

Children's privacy

Dyslexly can be used in schools and by children without creating a student account. The core reading controls do not send page content, reading settings or local reading statistics to Dyslexly. A Pro-trial email or optional onboarding answer should be submitted by a parent, guardian, teacher or an appropriately aged user who understands what is being provided.
