About this app

Provaki was created to help you gather, organize, and preserve digital evidence in a simple and structured way.

With the app, you can create separate cases, add photos, screenshots, PDFs, texts, and audio, record observations, and keep everything organized in a timeline.

When importing evidence, Provaki can store a copy in the app's private space and record its SHA-256 hash, helping to verify the file's integrity over time.

Key features include case organization, evidence history, date and time stamping, local storage, PDF report generation, and light and dark theme support.

Provaki is designed for situations where it's important to keep information organized, such as consumer relations, service provision, contracts, incidents, company problems, everyday conflicts, and other contexts where documents and records may need to be consulted later.

Data remains stored locally on the device in the current version of the app, without the need to create an account.

Important: Provaki is a tool for organizing and recording integrity. The use of the application, as well as SHA-256 hash recording, does not automatically guarantee the authenticity, admissibility, or legal validity of evidence. Evaluation depends on the context, the origin of the material, and the competent authority.

Provaki — your evidence, organized.
Organize digital evidence, record integrity, and generate reports.
