1. What is GDPR Scanner?

GDPR Scanner searches your organisation's digital data — emails, cloud files, shared drives, and local file servers — for personal data such as CPR numbers, names, addresses, phone numbers, and special-category data under GDPR Article 9.

When items are found, you can review them, decide what to do with each one (keep, delete, or note as out of scope), produce an Article 30 compliance report, and delete overdue data in bulk.

What it scans:

• Microsoft 365: Exchange email, OneDrive, SharePoint, Teams
• Google Workspace: Gmail, Google Drive
• Local and network file shares (including SMB/NAS drives)

What it finds:

• CPR numbers (Danish civil registration numbers)
• Phone numbers, email addresses, postal addresses
• Bank account and IBAN numbers
• Names and organisation names
• Photographs containing recognisable faces (optional)
• GPS location data embedded in image files

---

2. The Interface at a Glance

When you open the scanner, the screen is divided into three areas:

┌─────────────────┬──────────────────────────────────────────┐
│                 │  Top bar: Scan button, profiles, actions  │
│   Left sidebar  ├──────────────────────────────────────────┤
│                 │                                           │
│  - Sources      │         Results / scan progress           │
│  - Options      │                                           │
│  - Accounts     │                                           │
│  - Stats        ├──────────────────────────────────────────┤
│                 │               Activity log                │
└─────────────────┴──────────────────────────────────────────┘

Left sidebar — choose what to scan and how.
Top bar — start a scan, select profiles, and access exports and settings.
Results area — flagged items appear here as the scan runs.
Progress bar — sits just above the activity log and shows which source is being scanned, who is being scanned, and how far along the scan is.
Activity log — shows live status messages during scanning. Click the ▾ arrow in the log header to collapse or expand the panel. You can also filter the log to show only errors, copy all log text to the clipboard, and resize the panel by dragging the handle at its top edge.

Dark / Light mode

Click the 🌙 button in the top-right corner to switch between dark and light mode. Your preference is remembered.

---

3. Connecting to Your Data Sources

Before you can scan, you need to connect to at least one data source. Click the Sources button in the top bar to open the Source Management panel.

3.1 Microsoft 365

The Microsoft 365 tab shows your current connection status. If you see a green dot and your account or tenant name, you are already connected.

Sources you can enable or disable:

Toggle	What it scans
Outlook	Exchange mailboxes (inbox, sent, all folders)
OneDrive	Each user's personal cloud storage
SharePoint	Team and project sites
Teams	Files shared in Teams channels

Turn off any source you do not want to include. These settings are remembered.

3.2 Google Workspace

The Google Workspace tab lets you connect a Google Workspace (formerly G Suite) account via a service account, or a personal Google account via sign-in.

Sources you can enable or disable:

Toggle	What it scans
Gmail	All emails in each user's inbox and labels
Google Drive	All files owned by or shared with each user

3.3 Local and Network File Shares

The Filkilder (File Sources) tab lists any local folders or network drives you have configured.

To add a new file source:

1. Enter a Label — a friendly name you will recognise (e.g. "Skolens Fællesmappe").
2. Enter the Path:
   • Local folder: ~/Documents or /Volumes/Share
   • Network share: //nas-server/shared or \\server\share
3. If it is a network share, fill in the SMB Host, Username, and Password that appear automatically. The password is stored securely in your system keychain.
4. Click Tilføj (Add).

You can add as many file sources as you need. Each one will appear as a selectable source in the main sidebar when you are ready to scan.

---

4. Running a Scan

4.1 Select Your Sources

In the left sidebar under Kilder (Sources), tick the sources you want to include in this scan. You can mix M365, Google, and file sources in the same scan.

4.2 Choose Your Accounts

Under Konti (Accounts) the sidebar shows all users connected to your M365 and/or Google tenant.

• Use the search box to find specific people.
• Use the Alle / Ansat / Elev buttons to filter by role.
• Use the Alle and Ingen buttons to select or deselect everyone at once.
• Tick or untick individual names.

For file sources, accounts are not relevant — all files in the selected paths are scanned.

4.3 Configure Options

Under Indstillinger (Options) you can refine the scan:

Date filter (Scan e-mails/filer fra)
Only scan items modified after a certain date. Quick presets — 1 år, 2 år, 5 år, 10 år, Alle — let you choose a window with one click. You can also pick a specific date with the date picker.

Tip: Starting with "2 år" is a good first scan. You can always widen to "Alle" later.

Email body — scan the text content of emails. On by default.

Attachments — scan files attached to emails. On by default.

Max attachment size — skip attachments larger than this limit (default 20 MB). Increase it if you want to check large documents.

Max emails per user — stop after scanning this many emails per person (default 2,000). Increase if you need complete coverage.

4.4 Start the Scan

Click the blue Scan button in the top bar.

A progress bar appears showing:

• A coloured source label — Outlook, OneDrive, SharePoint, Teams, Gmail, GDrive, or Local — followed by the full name of the account currently being scanned
• A live count of items scanned and flagged
• An estimated time remaining

Results appear in the main area as they are found — you do not need to wait for the scan to finish before reviewing them.

To stop a scan, click Stop. A checkpoint is saved automatically so you can resume later.

4.5 Resuming an Interrupted Scan

If a scan was interrupted (by a stop, a crash, or closing the application), a yellow banner appears at the top of the results area:

Previous scan interrupted — X scanned, Y found ▶ Genoptag · Start fresh

Click ▶ Genoptag to continue from where the scan left off. Click Start fresh to discard the checkpoint and begin again.

---

5. Understanding the Results

Each flagged item appears as a card. Here is what the badges and labels mean:

Source badges

Badge	Meaning
Outlook	Found in an Exchange mailbox
OneDrive	Found in a user's OneDrive
SharePoint	Found in a SharePoint site
Teams	Found in a Teams channel
Gmail	Found in a Gmail mailbox
Google Drive	Found in Google Drive
Local / Network	Found on a file share

Risk level

Level	Meaning
HIGH	Multiple CPR numbers, special-category data, older than retention policy, or externally shared
MEDIUM	Single CPR with some sharing or contextual risk
LOW	Single CPR number, not shared, recent

Other badges

Badge	Meaning
Number (e.g. 3)	Number of CPR numbers found in this item
Delt (Shared)	The item has been shared with other users
Ekstern (External)	The item has been shared with someone outside your organisation
Art. 9	Special-category data detected (health, religion, biometric, etc.)
N faces	N recognisable faces detected in a photo
GPS	The file contains GPS location data in its metadata

Grid view vs. list view

The default grid view shows cards. Click List in the filter bar to switch to a compact table view with sortable columns. Click Grid to switch back.

Filtering results

Use the filter bar above the results to narrow down what you see:

• Search box — search by name, subject, or path.
• Source dropdown — show only one source type.
• Disposition dropdown — show items by their review status.
• Transfer dropdown — filter by shared / external / all.
• Risk dropdown — show only Art. 9, photos, GPS, or high-risk items.

---

6. Reviewing and Tagging Results

Click any result card to open the preview panel on the right side of the screen.

The preview shows:

• The item name or email subject
• The account (owner / sender)
• Source and modification date
• All CPR numbers found and their context
• Other personal data detected (phone, email address, IBAN, etc.)
• Sharing and external-access information

Setting a disposition

Every item has a Disposition dropdown in the preview panel. Choose one of:

Disposition	Use when…
Ikke gennemgået (Unreviewed)	Not yet assessed — the default
Opbevar — lovkrav	You must keep it by law
Opbevar — legitim interesse	You have a legitimate interest in keeping it
Opbevar — kontrakt	Required for a contract
Slet — planlagt	Marked for future deletion
Privat brug — uden for scope	Personal item, not in scope for GDPR processing
Slettet	Already deleted (set automatically when you delete an item)

After choosing, click Gem. A small ✓ Gemt confirmation appears.

Finding all items for a specific person

Click 🔍 in the sidebar (under Stats) to open the Data Subject Lookup. Enter a CPR number and the scanner will find all flagged items containing that number. You can then delete all of them in one step — supporting the GDPR right to erasure (Article 17).

The CPR number is hashed before the search and is never stored in plaintext.

---

7. Deleting Items

7.1 Deleting a Single Item

With an item open in the preview panel, set its disposition to Slet — planlagt, then use the action button to delete it. The item moves to the Deleted Items folder (email) or recycle bin (files).

7.2 Bulk Delete

Click the Delete button in the filter bar to open the bulk delete modal.

1. Set filters to target the items you want to delete:

   • Source type — delete from one source or all.
   • Min. CPR hits — only delete items with at least this many CPR numbers.
   • Older than date — only delete items modified before a specific date.
   • Click 🗓 Filter overdue to automatically fill in the date based on your retention policy.

2. The modal shows how many items match your filters.

3. Click the red Delete matching items button to proceed.

4. A progress bar shows deletions as they happen. Emails go to Deleted Items; files go to the recycle bin.

A full audit log of every deletion (what was deleted, when, and why) is included in the Article 30 report.

---

8. Profiles — Saving Your Scan Settings

A profile stores your chosen sources, accounts, scan options, and date settings so you can re-use them without reconfiguring every time.

Saving a profile

Configure the sidebar exactly as you want it — including which M365 sources, Google sources, and local file sources are enabled, which accounts are selected, and all options — then click the Save button in the top bar. Enter a name and click OK. The profile is saved and selected immediately.

Applying a profile

Click the profile dropdown in the top bar and select a profile. All sidebar settings — sources, accounts, options, and date filter — are loaded at once. The sidebar then shows your live state and you can adjust anything before scanning.

A Clear button appears next to the dropdown after you select a profile. Click it to clear the profile label without changing the sidebar settings. This is useful when you want to run a one-off scan without overwriting a saved profile.

Managing profiles

Click Profiles to open the profile management panel. Here you can:

• Edit any profile — change its name, description, sources, accounts, or options.
• Duplicate a profile — useful as a starting point for a variation.
• Delete a profile.

Note: Editing a profile does not affect scans already completed with that profile.

---

9. Reports and Exports

9.1 Excel Export

Click Excel in the filter bar to download the current results as an Excel workbook. The workbook contains:

• A summary tab with scan date, item counts, and source breakdown.
• A separate tab for each source type (Outlook, OneDrive, SharePoint, Teams, Gmail, Google Drive, Local, Network).
• Every flagged item, including source, account, CPR count, risk level, sharing status, and disposition.

The Excel and Art.30 buttons are always available — even after restarting the application — and will export the results from the most recent completed scan session without requiring a new scan.

The Excel file is the main working document for your internal review process.

9.2 GDPR Article 30 Report (Word document)

Click Art.30 in the filter bar to generate a Word document that satisfies the GDPR Article 30 requirement to maintain a record of processing activities.

The document includes:

• Executive summary — scan date, total items, CPR counts per source.
• Data categories — which types of personal data were found.
• Data inventory — the full list of flagged items.
• Retention analysis — items older than your retention policy, with a breakdown by source.
• Special-category data (Art. 9) — health, biometric, and other sensitive data found.
• Photographs / biometric data — if face scanning was enabled.
• GPS data — files with embedded location information.
• Compliance trend — flagged counts across your last 20 scans.
• Deletion audit log — a complete record of all deletions made through the scanner.
• Methodology — how the scan was performed and the legal basis for scanning.
• Notes on student data — guidance on parental consent requirements for children under 15.

10. Sharing Results with a Reviewer

You can give a DPO, school principal, or compliance coordinator read-only access to the results grid — including the ability to tag dispositions — without giving them access to scan controls, credentials, or settings.

10.1 Token links

Click the 🔗 button in the top-right of the top bar to open the Share panel.

1. Optionally enter a Label to identify who the link is for (e.g. "DPO review April 2026").
2. Choose an Expiry — 7 days, 30 days, 90 days, 1 year, or Never.
3. Click Create. A unique link is generated: http://host:5100/view?token=…
4. Click Copy to copy the link to your clipboard, then send it to the reviewer.

The reviewer opens the link in any browser. They see the full results grid and can tag dispositions but cannot start scans, change settings, view credentials, or delete items.

Managing existing links

The Share panel lists all active links. Each row shows the label, expiry date, and when the link was last used. Click Copy to copy a link again, or Revoke to invalidate it immediately.

10.2 Viewer PIN

As an alternative to token links, you can set a numeric PIN (4–8 digits) in Settings → Security → Viewer PIN. Anyone who knows the PIN can open http://host:5100/view in a browser, enter the PIN, and access the read-only view for the duration of their browser session.

To set or change the PIN, enter the new PIN in the New PIN field and click Save PIN. To remove it, click Clear PIN.

Security note: Token links are more secure than a PIN because each link can be individually revoked and has an expiry date. Use the PIN option only for trusted internal reviewers on your local network.

10.3 What the reviewer can do

Action	Allowed
Browse results grid	Yes
Filter and search results	Yes
Open item preview	Yes
Tag dispositions	Yes
Export to Excel	Yes
Export Article 30 report	Yes
Start or stop a scan	No
View or change credentials	No
Delete items	No
Access Settings	No
Create or revoke viewer links	No

---

11. Scheduled Scans

Go to Settings → Planlægger to configure automatic scans.

Creating a scheduled scan

1. Click + Tilføj planlagt scanning (+ Add scheduled scan).
2. Give the job a name.
3. Choose the frequency: Dagligt, Ugentligt, or Månedligt.
4. For weekly scans, choose the day of the week. For monthly, choose the day of the month.
5. Set the time the scan should run.
6. Choose a Profile — the scanner will use that profile's sources, accounts, and options.
7. Optionally enable:
   • Send rapport automatisk — email the Excel report to your configured recipients after each scan.
   • Håndhæv opbevaringspolitik — automatically delete items older than your retention policy after each scan.
8. Click Gem (Save).

The scheduler indicator in the top bar shows the date and time of the next scheduled scan ("Next: …").

Viewing recent runs

The scheduler tab shows a history of recent runs, including start time, status, and the number of items flagged.

---

12. Email Reports

Go to Settings → E-mailrapport to configure email sending.

Setting up SMTP

Fill in your outgoing mail server details:

Field	Example
SMTP host	smtp.office365.com
Port	587
Username	scanner@skole.dk
Password	(your email password or app password)
From address	scanner@skole.dk
Recipients	dpo@skole.dk; it@skole.dk

Click Gem to save, then click Test to send a test email and verify the configuration is working.

If your account has MFA (two-factor authentication) enabled, you cannot use your regular password. You need to create an App Password in your account security settings:

• Microsoft personal account: account.microsoft.com/security → App passwords
• Gmail: myaccount.google.com → Security → 2-Step Verification → App passwords

Sending a report manually

Click Send nu (Send now) to email the current Excel report immediately to all configured recipients.

---

13. Database Backup and Restore

All scan results, dispositions, and the deletion audit log are stored in a local database. It is good practice to take regular backups.

Go to Settings → Database.

Backup (Export)

Click Export to create a .zip backup of your database. Save it to a safe location.

Restore (Import)

Click Import to restore from a backup. Two modes are available:

Mode	When to use
Merge (safe)	Add dispositions and deletion log from the backup to your existing data. Use this to consolidate data from multiple installations.
Replace (full restore)	Erase everything and restore the backup completely. Use this to move to a new machine or recover from data loss. Requires Admin PIN confirmation.

Reset database

Click Reset DB to wipe all scan data, dispositions, and deletion log. This is irreversible. If an Admin PIN is set, you must enter it to proceed.

---

14. Settings Reference

General tab

Setting	Description
Theme	Dark or light mode

Security tab

Setting	Description
Admin PIN	Optional PIN that protects destructive actions (database reset, replace import)
Viewer PIN	Optional 4–8 digit PIN that lets anyone open /view in a browser for read-only access to results without a token link

Advanced scan options

These options are in the left sidebar under Indstillinger:

Delta scanning — after your first full scan, enable this to scan only items that have changed since the last scan. Much faster for routine checks. A "Clear tokens" button forces the next scan to be a full scan.

Scan photos for faces — slower scan that detects photographs containing recognisable human faces. Flags them as Article 9 biometric data. Recommended for schools storing student photos.

Ignore GPS in images — when enabled, images whose only PII signal is an embedded GPS location are not flagged. Useful when scanning student accounts: smartphones embed GPS coordinates in every photo taken with the camera app, which would otherwise generate large numbers of flags that are low-priority for a school context. If an image is already flagged for another reason (faces, EXIF author field), the GPS coordinate is still shown in the detail card.

Min. CPR count per file — only flag a file if it contains at least this many distinct CPR numbers. The default is 1 (current behaviour). Setting it to 2 avoids false positives in student scans: a student's own consent form or registration document typically contains only their own CPR number, while a class list or grade sheet containing multiple students' CPRs will still be reported.

Retention policy — when enabled, marks items older than the specified number of years as overdue. The fiscal year end setting determines how the cutoff date is calculated:

Option	Cutoff date calculation
Rolling (fra i dag)	Today minus N years
31 dec (Bogføringsloven)	Last 31 December minus N years
30 jun / 31 mar	Last occurrence of that date minus N years

---

15. Frequently Asked Questions

Does the scanner store CPR numbers?
No. CPR numbers found during a scan are stored only as a count (e.g. "3 CPR numbers found") and as a SHA-256 hash used for the Data Subject Lookup. The actual number is never written to the database.

What happens when I delete items through the scanner?
Emails are moved to the user's Deleted Items folder in Exchange — they are not permanently deleted and can be recovered by the user or an administrator. Files are moved to the recycle bin of the relevant service (OneDrive, SharePoint, file system). A permanent deletion requires a second action by the user or admin.

Can I scan without connecting to Microsoft 365?
Yes. You can scan local and SMB file shares without any M365 or Google connection. Open Sources, go to the Filkilder tab, and add your file paths.

What is delta scanning and when should I use it?
Delta scanning uses Microsoft Graph change tokens to fetch only items modified since the last scan. It is ideal for regular (e.g. weekly) compliance checks after you have done a full baseline scan. Enable it in the Options section of the sidebar.

The scan stopped — can I continue where it left off?
Yes. When you restart the scan, a yellow banner will offer to resume from the checkpoint. Click ▶ Genoptag to continue. If you prefer to start over, click Start fresh.

How do I prove compliance if we are audited?
Use the Art.30 button to export the Article 30 report. It is a Word document covering your data inventory, retention analysis, deletion log, and methodology — exactly what a supervisory authority (Datatilsynet) typically requests.

What does the "Elev / Ansat" filter do?
The scanner classifies users as staff (Ansat) or students (Elev) based on their Microsoft 365 licence type or Google Workspace organisational unit. You can use this filter in the accounts list to restrict a scan to only staff, only students, or a specific individual. This is useful because the rules for processing student data — especially for children under 15 — differ from staff data under Databeskyttelsesloven.

How do I add an account that is not in the list?
In the accounts section of the sidebar, there is an + Tilføj konto manuelt (Add account manually) field. Enter the email address or UPN and it will be added to the current session's account list.

Is the scanner running? I cannot see a progress bar.
Check the activity log at the bottom of the screen. If a scan is running it will show messages there. If you see nothing, the scan may have completed or not started. Also check that you have at least one source ticked and at least one account selected.

Can a reviewer tag dispositions without access to the scan controls?
Yes. Use the 🔗 Share button to create a read-only viewer link or set a Viewer PIN in Settings → Security. The reviewer opens the link in their browser and can browse results and tag dispositions without seeing credentials, sources, or scan buttons. See section 10 for details.
