A note is a convenience. A chart is evidence.
Nobody thinks about this until something happens. A patient bruises badly and asks what was used. A complaint arrives fourteen months after a treatment. An insurer wants documentation. At that point the question is not whether you wrote something down, but whether what you wrote can be relied on.
Zdrovia keeps revisions. If a note is amended the earlier version stays, timestamped and attributed. Consent forms are versioned separately, so you can show the exact wording a patient signed rather than the wording currently on your form.
Photos live on the chart as dated pairs, encrypted at rest, with the consent for clinical use recorded separately from consent for marketing use. Those are different permissions and treating them as one is a common and avoidable mistake.
