Active internet users aged 55-65 have an average of 30-50 online accounts (financial, shopping, social media, subscription services, cloud storage), but in the event of their death, their families are not even aware of these accounts. Unresolved paid subscriptions continue to be auto-charged monthly, and photos and documents stored in the cloud become permanently inaccessible. Currently, there is no Korean-language service to systematically organize this, so people rely on insecure methods like writing passwords in notepads or on paper.
Solution
An encrypted web service that allows users to register their digital accounts, subscriptions, and assets by category and grant designated family members viewing access. Key features: (1) registration and notes by account type (financial/shopping/SNS/subscription/cloud), (2) does not store passwords but only records hints on 'where to find them', (3) sends access instructions to designated family members via email/text. Differentiator: minimizes security risk by not storing passwords themselves.
Target: Retirees-to-be aged 55-65 with multiple online accounts who want to pass on digital asset information to their spouse or adult children.
Revenue Model: Free for up to 10 accounts. Unlimited registration + family sharing for 2,900 KRW/month (approximately $2.20). PDF summary download: 1,900 KRW per download (approximately $1.40).
