Always know where your data goes

Every tool shows whether it runs in the browser, in the Seeft cloud or through a connected service. The data flow is stated explicitly.

Learn about our privacy approach

Local

Input and output remain in the browser. This is the model used by the currently published tools.

Seeft Cloud

When a server is needed, the tool will state the purpose and retention period before use.

Connected service

Integrations will send data to the provider selected by the user and clearly describe the flow.

Frequently asked questions

Do I need an account?

Not for free tools that do not need to save data. It will be required for suggestions, presets, subscriptions and connected features.

Is my data uploaded to a server?

It depends on the tool. Tools marked Local run in your browser. Cloud or connected tools explain which data is transmitted.

Will every suggested tool be built?

No. Suggestions are evaluated for broad usefulness, sustainability, security and fit with Seeft.

Who can use a tool created from a suggestion?

The tool becomes part of the shared product. It may be Free or Pro and is not exclusive to the person who suggested it.

How much will Pro cost?

Pricing will be published when the first Pro features are ready and can be evaluated.
