7 Apr 2026 Wspólnota Mieszkaniowa K. (Wohnungseigentümergemeinschaft, im Bescheid pseudonymisiert)Homeowners’ association: 4,852 PLN – misdirected statement not notified €1,135
Acting as processor, the property management company sent an owner’s statement of service charges to an unauthorised person. The association considered notification unnecessary because only ‘ordinary’ data of one member were affected, and maintained this position in the proceedings; the UODO (Poland’s data protection authority) imposed 4,852 PLN.
Small controllers must also assess and notify data breaches by their service providers – ‘only one data subject’ is no ground for exemption.

23 Oct 2025 Komornik Sądowy przy Sądzie Rejonowym w S. (Gerichtsvollzieherkanzlei, im Bescheid pseudonymisiert)Bailiff: 20,900 PLN – documents with PESEL number misdirected, not notified €4,938
In October 2023, an uninvolved person received a debtor’s enforcement documents containing name, address, date of birth, PESEL number, amount of the claim and employer. The bailiff’s office neither notified the supervisory authority nor informed the data subject; the UODO (Poland’s data protection authority) imposed 7,700 PLN for the failure to notify and 13,200 PLN for the failure to inform the data subject, and ordered the data subject to be informed within three days.
Where identification numbers such as the PESEL number are disclosed, a high risk can almost always be assumed – notification of the authority and of the data subject is then mandatory.

12 Mar 2024 Santander Bank Polska S.A.Santander Bank Polska: 1.44 million PLN – stolen customer documents not reported €336,066
A courier consignment containing bank documents (including PESEL numbers, account numbers, login credentials) was stolen and discarded on a housing estate; the supervisory authority learned of it from the media. The bank had informed neither the authority nor the data subjects because it rated the risk as low – it had already been sanctioned in 2022 for failing to notify data subjects.
Assess the risk of a data breach from the data subjects’ perspective – failing to notify the loss of sensitive documents risks a higher penalty than the breach itself.

12 Mar 2024 Toyota Bank Polska S.A.Toyota Bank Polska: 78,575 PLN – misdirected mailing reported only after 1.5 years €18,331
The bank sent a customer’s contract data to the wrong recipient and only reported the breach one and a half years later, when the supervisory authority made enquiries following a complaint. Given the risk of identity theft, the authority considered that there had been an obligation to notify within 72 hours.
Even a single misdirected mailing containing identity data is notifiable – misdirected mail cases need a documented risk assessment.

18 Oct 2023 Link4 Towarzystwo Ubezpieczeń S.A.Link4: 103,752 PLN – misdirected e-mail not reported after using a risk calculator €23,362
The insurer sent a claims settlement confirmation containing name, address, vehicle and claim data by e-mail to an unauthorised person. After an assessment using an online calculator, it rated the risk as low and did not notify; the supervisory authority found that the notification obligation had been breached and treated, among other things, intent and lack of cooperation as aggravating factors.
Risk assessment tools do not replace judgement – anyone sending out information covered by insurance secrecy should notify if in doubt.
