What Readback does with your reading, what leaves your device, and how to remove it.

What stays on your device

Reading activity. Active reading time and scroll depth for articles on technical sites are kept on your device.
Article text. Kept article text stays on the device that kept it. Another device can show questions and results but cannot write new questions from text it does not have.
Not tracked. Shopping, social, video and search pages.

Only kept articles. The text of articles you keep is sent to write questions, and only with your consent. Consent is a separate setting.
Grading. If you ask for a written answer to be graded, the question, the reference passage and your answer are sent for grading, with your consent.
Not stored. Readback's server does not store article text, prompts or replies.
No AI account. Readback provides the AI. You never bring a key or create an AI account.

No account is needed for tracking, Keep and the local dashboard. An account (email and password, Readback sign up only) is needed for AI question writing, AI grading and sync.
Passwords are stored only as salted hashes. Sessions last 30 days.
Password reset is not available yet.

Off by default. Sync is a separate, explicit choice and needs an account.
What syncs. Article metadata (address, title, domain, active seconds, scroll percentage, word count, last read, kept, never quiz), question sets, cards and their schedule, answer results (correct or incorrect, time), and settings flags (tracking, deny list).
Never synced. Full article text, your typed short answers, raw events and passwords.

Anonymous product counts are a separate opt in, off by default. They never include addresses, titles or text.

On this device. Delete local data from Readback settings.
In the cloud. Delete all synced rows. If Sync is on, deleting your history asks whether to delete cloud data too.
Your account. Delete the account, its sessions and all of its data.
