An honest mandatory checklist for German HR teams. No lawyer language, no 'might possibly' - just: do this, don't do that.

Key takeaways
Default 6 months from rejection. Per candidate you can extend with consent. Anonymisation at end of window is automatic.
Plain language: 'Your data is stored for the application, anonymised after 6 months. KI pre-sorting is used; a human always decides.' No 14 pages, one paragraph is enough.
Look at your application form. Do you really need date of birth, photo, marital status? If no, remove. For every field you ask, you must be able to justify why.
If someone asks 'what data do you have on me?', it must be answered in 30 days. One-click export on the candidate detail page suffices.
On by default in KI BMS. Who changed what when - the only answer that holds under anti-discrimination law to 'who decided this?'.
A concrete, factual rejection is legally safer than a vague one. Template: 'For this role we need 3+ years Python backend; your focus is frontend.' Concrete > nice.
Four cores. One - lawful basis (typically: consent or pre-contract). Two - purpose limitation: application data only for application purposes. Three - data minimisation: don't ask more than needed. Four - retention limit: don't keep data longer than needed.
Plus two procedural duties: information before collection, access on request. The rest are special cases (special categories like health, third-country transfer, etc.). A practical breakdown is in our article GDPR in recruiting - what you actually have to do.
In concrete articles: the lawful basis for the normal procedure is Art. 6(1)(b) GDPR (pre-contract), flanked by § 26(1) BDSG as the employee-data norm. Important in 2026: the ECJ (C-34/21) declared § 26 BDSG partly incompatible with EU law, so the safe footing is directly on Art. 6(1)(b) + Art. 88 GDPR. Special data (photo, health) falls under Art. 9, information under Art. 13/14, access under Art. 15 (deadline: 1 month), erasure under Art. 17, the auto-decision ban under Art. 22, the DPA under Art. 28, the record of processing under Art. 30, the technical/organisational measures under Art. 32.
The most-asked question has a clean answer. A rejected applicant can claim discrimination compensation under § 15(4) AGG within 2 months. If it goes to court you need the application file as evidence - the legitimate-interest basis to keep it beyond the 2 months. Add litigation and postal time and authorities land on 6 months from rejection as the safe default. In Austria it's closer to 7 months because of § 29 GlBG.
It also means: deleting earlier isn't extra safety, it's an evidence risk. And keeping it longer without grounds is the breach authorities cite most. The 6-month window with automatic anonymisation at the end is therefore the calmest path - exactly what KI BMS does per candidate automatically.
Myth 1 - 'We need a consent checkbox for every application.' Wrong. The normal hiring procedure runs on Art. 6(1)(b) GDPR; consent is superfluous and even problematic because it would be revocable at any time. You only need explicit consent for the talent pool (storage beyond the procedure) - and it must be voluntary, time-limited (authorities recommend 1-2 years), and revocable at any time.
Myth 2 - 'Photo and date of birth belong on the application form.' No. Data minimisation (Art. 5) means: ask only what's relevant to the role. A photo, birth date, marital status, religion almost never are - and a required photo is an AGG discrimination risk on top. If a photo arrives in the CV, use it only within the procedure and don't put it in presentations or databases.
Myth 3 - 'Third-country transfer doesn't affect us.' It does, the moment your ATS, sourcing tool, or mail provider mirrors data to the US. Then you need a transfer basis (the EU-US Data Privacy Framework adequacy decision or standard contractual clauses under Art. 44 ff.). The simplest way to avoid the topic entirely: an EU-hosted tool. KI BMS hosts in Germany and provides the Art. 28 DPA on request within one business day.
