Your practice data
Reading marks, course progress and practice tasks are stored only in this browser on this device. They are not synchronized or backed up to an account. Other people using this browser profile can see them. Clearing site data removes them. Do not enter private, client, patient, workplace or password information.
Practice, not certification
The hosted task and capstone tools are browser simulations. Chapters also teach a separate local Python and SQLite application. A browser exercise does not run that server or prove its database, security or production behavior. Checkpoint answers are delivered to the browser as teaching material, not protected exams. Completing lessons is not a professional certification or proof of job readiness.
Sources and costs
Sources and capture dates remain attached to the lessons. Vendor features, prices and availability can change. Links to outside training may involve accounts, paid exams, software or cloud services. Read current provider terms before signing up or spending. Learning guidance is not a guarantee of employment.
Privacy and safe practice
This edition has no advertising, analytics, email collection or AI API calls. The hosting provider processes ordinary web requests. External links use the destination provider's policies. Practice security techniques only in your own lab or with explicit written authorization.
