Vendor termination data return and deletion procedures per GDPR Article 28(3)(g).

  • Works in 3 steps: Data Inventory and Mapping → Data Export Format and Method → Data Validation
  • Tasks that involve Privacy and GDPR
  • SKILL.md covers Overview, Termination Triggers, Data Return Process and Data Deletion Process, plus 3 more sections
  • Runs Python scripts from its folder

What it does

Vendor Termination Data is an agent skill from mukul975/Privacy-Data-Protection-Skills. Vendor termination data return and deletion procedures per GDPR Article 28(3)(g). Covers data extraction formats, deletion certification requirements, transition planning, residual data handling, and post-termination verification.

Its SKILL.md is about 2.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 7 other files, including scripts, reference files and assets (for example `assets/template.md`, `references/standards.md` and `references/workflows.md`).

It sits in Legal & Compliance, covering Privacy and GDPR. The repository describes itself as: 282+ structured privacy & data protection skills for AI agents. GDPR, CCPA, EU AI Act, HIPAA, LGPD, PIPL, DPDP Act. The licence is Apache-2.0.

When your agent uses it

  • Tasks that involve Privacy and GDPR

Example prompts

  • “/vendor-termination-data”

Requirements

  • Python 3

Workflow steps

3 steps, taken from the step headings in SKILL.md.

  1. Data Inventory and Mapping
  2. Data Export Format and Method
  3. Data Validation

What it can do on your machine

Read from SKILL.md and the folder at commit 9b2ef9e. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 1 file in scripts/ (Python), which the agent can run.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Vendor Termination Data loads about 2.3k tokens when it runs, and up to ~4.4k if it reads all its reference files. Until then it costs about 64 tokens; SKILL.md has 988 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~64
When it runs · the whole SKILL.md, loaded when a task matches
~2.3k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~4.4k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

Vendor Termination Data Return and Deletion

Overview

GDPR Article 28(3)(g) requires that at the choice of the controller, the processor shall "delete or return all the personal data to the controller after the end of the provision of services relating to processing, and delete existing copies unless Union or Member State law requires storage of the personal data." This termination obligation ensures that personal data does not persist at a former processor beyond the legitimate processing period.

The EDPB Guidelines 07/2020 (paragraph 108) emphasize that this obligation extends to all copies, backups, and derived data — not just production data. The deletion must be verifiable, and the controller should obtain written certification.

At Summit Cloud Partners, the Vendor Termination Data Protocol provides a structured process for managing data return and deletion when vendor relationships end.

Termination Triggers

TriggerDescriptionTimeline Considerations
Contract expiry (non-renewal)MSA/DPA term ends without renewal90-day notice per DPA
Termination for convenienceController elects to terminatePer MSA notice period
Termination for causeMaterial DPA breach by processorImmediate or per cure period
Service migrationController moves to alternative providerOverlap period for data migration
Vendor insolvencyProcessor enters insolvency proceedingsEmergency data retrieval
Regulatory orderSupervisory authority orders cessationPer order timeline

Data Return Process

Step 1: Data Inventory and Mapping

Before initiating return, confirm the complete scope of personal data held by the processor:

Data CategoryLocationFormatVolumeRetention Basis
Production dataPrimary databaseStructured (SQL/JSON)[Volume]DPA processing
Backup dataBackup storageEncrypted backup files[Volume]Business continuity per DPA
Log dataLog storageSemi-structured (JSON/text)[Volume]Security monitoring
Derived/aggregated dataAnalytics systemStructured[Volume]Processing output
MetadataVarious systemsStructured[Volume]System operation
Cached dataCDN/cache layersVarious[Volume]Performance
Step 2: Data Export Format and Method

Standard Export Formats:

Data TypePreferred FormatAlternative FormatNotes
Structured dataCSV with defined schemaJSON, XML, ParquetUTF-8 encoding required
DocumentsOriginal format (PDF, DOCX)ZIP archivePreserve directory structure
Images/mediaOriginal format (PNG, JPEG)ZIP archivePreserve metadata
LogsJSON lines (JSONL)CSVInclude timestamps
API-accessible dataDirect API extractionBulk export endpointPaginated if large

Export Methods:

MethodWhen to UseSecurity Requirements
Encrypted file transfer (SFTP)Large datasetsTLS 1.2+, PGP encryption
Secure API extractionStructured, API-accessible dataOAuth 2.0, TLS 1.3
Encrypted portable mediaVery large datasets without bandwidthAES-256 encryption, tracked courier
Cloud-to-cloud migrationCloud provider transitionEncrypted transfer, access audit
Step 3: Data Validation

Upon receiving returned data, Summit Cloud Partners validates:

Validation CheckMethodPass Criteria
CompletenessRecord count comparisonReturned count matches source count
IntegrityChecksum verification (SHA-256)Checksums match vendor-provided manifest
Format complianceSchema validationAll fields present per agreed schema
EncodingCharacter encoding verificationUTF-8 without corruption
Sample verificationRandom sample manual reviewData content matches expectations

Data Deletion Process

Deletion Scope

The processor must delete ALL copies of personal data, including:

  1. Production data — Primary databases and data stores
  2. Backup data — All backup copies including off-site backups
  3. Disaster recovery copies — DR site data
  4. Log data — Application logs, access logs, audit logs containing personal data
  5. Cached data — CDN caches, application caches, database caches
  6. Derived data — Analytics outputs, aggregated data containing personal data
  7. Metadata — System metadata referencing personal data
  8. Archived data — Any archived copies
  9. Sub-processor data — Data at all sub-processors

T+60 to T+90Backup and archive deletion90 calendar days from termination
T+90Deletion certification issued90 calendar days from termination
Deletion Exceptions

Article 28(3)(g) permits continued storage where "Union or Member State law requires storage of the personal data." Exceptions must be:

RequirementProcessor Action
Documented in writingProcessor identifies specific legal requirement
Limited to required dataOnly data subject to legal retention requirement
Isolated from productionRetained data moved to restricted storage
Time-limitedRetained only for legally required duration
Notified to controllerController informed of retention and legal basis

Deletion Certification

The processor must provide a written deletion certification containing:

FieldContent
Certifying partyName and title of authorized processor representative
Controller nameSummit Cloud Partners
DPA referenceReference to terminated DPA
Deletion scopeDescription of all data deleted (categories, locations, formats)
Deletion date(s)Date each deletion action was completed
Deletion method(s)Technical method used for each data location
Sub-processor deletionConfirmation that all sub-processors have also deleted data
ExceptionsAny data retained under legal obligation (with legal basis citation)
Certification dateDate of certification
SignatureAuthorized officer signature

Transition Planning

For service migrations, a transition plan ensures continuity while managing data protection obligations:

PhaseActivityDuration
PlanningDefine data migration scope, format, timeline4-6 weeks

MigrationData transferred from old to new vendor1-2 weeks
