Account and data deletion
Last updated: 27 July 2026
This page explains how to delete your ControlliQ user account and the data associated with it. ControlliQ is developed and operated by Composite Solutions Hungary Kft. The ControlliQ mobile app and the web interface use the same account, so deletion covers both at once.
How to request deletion
You can start the process in two ways. Both lead to the same place and both are free of charge.
Fill in the "Deletion request" form using the e-mail address registered to your account. The request goes directly to our data protection team.
Write to team@controlliq.com with the subject "Account deletion", from the e-mail address registered to your account. Please also include your company name or tax number so we can identify the account.
What happens after you submit a request?
• We acknowledge the request within 5 business days, to the e-mail address it was sent from. • We identify the account and tell you if your account is the sole administrator of a company. • We carry out the deletion within 30 days of the acknowledgement at the latest. • We send a separate e-mail once the deletion is complete. • Data disappears from backups when the backup cycle expires, and within a further 30 days at the latest.
What data is deleted?
• Core account data: name, e-mail address, password, phone number, profile picture. • Sign-in data: password hash, linked Google/Microsoft accounts, two-factor authentication settings. • Access tokens issued to the app and the device identifiers stored for push notifications. • Notification history and in-app settings. • Conversations with the AI assistant and their history. • Your newsletter subscription, including in our mailing system. • The link between you and the entries in the financial change history. The entries themselves stay with the company — the other users and the auditability of the accounts depend on them — but they can no longer be attributed to you. • If the user is the sole administrator of the company and the request covers the company as well: uploaded documents, scanned invoice images, invoice and financial records, the partner directory, cost centres and bank statements.
What data is retained, and for how long?
Some data must be retained despite a deletion request, because the law requires it: • Invoices issued for your ControlliQ subscription and the related accounting records: for 8 years from issuance (Hungarian Act C of 2000 on Accounting, Section 169). • Billing data required for tax purposes: for 8 years. • Data needed to establish or defend legal claims, until the end of the general limitation period, that is 5 years (Hungarian Civil Code, Section 6:22). • Anonymised usage statistics that can no longer be linked to a person — after deletion these are not personal data, so they may be retained indefinitely. If your account belongs to a company that has other users, we delete only your personal data. The company's financial and invoice data stays with the company, because the company is the controller for that data — ControlliQ acts as a processor in that case.
Your other rights
Beyond deletion, you can also request access to your data, its rectification, restriction of processing, and data portability. You can raise any of these at the same e-mail address. If you believe our processing infringes your rights, you may lodge a complaint with the Hungarian National Authority for Data Protection and Freedom of Information (NAIH, 1055 Budapest, Falk Miksa utca 9-11., ugyfelszolgalat@naih.hu), or turn to the courts. Our Privacy Policy describes our processing in detail.
