Who this covers
The people who report faults. A technician is staff on your payroll; the person who rang to say the compressor was making a noise may be a tenant, a customer or a member of the public, and their name and contact sit on the customer record. That is the personal data Jobora holds.
1 · Subject access — export everything held
2 · Erasure — remove someone's contact details
Their name, contact name, email, phone, address and notes are replaced with [removed] on the customer record, and so are the site address on their jobs and recurring plans, the public booking request a job came from, and the texts and emails sent to them.
The jobs themselves stay. What was quoted, what was done, what it cost and what was invoiced is the business's own trading record — the thing your accounts rest on and the thing a dispute is settled with.
Kept: the customer's sign-off on a job (the name, role, statement and signature, and the address it was signed from), the name typed to accept a quote, and the audit trail's lines that the customer was added or edited, because the sign-off and the acceptance are the evidence a dispute is settled with and the audit trail cannot be edited.
Jobora refuses while any of their jobs is still open, because somebody may still need to ring them what happened.
