Calculations and values
Tollica's interactive tools perform their normal calculations in your browser. Values and planning inputs you enter are not submitted to a separate calculation service.
When you choose Share, Tollica may place a snapshot of the tool inputs in the URL fragment: the part after the # symbol. Browsers do not send that fragment in a normal HTTP request to Tollica or its host. The complete link can still be seen by its recipients and may remain in browser history, clipboards, messaging services, or other software used to share it. Do not place confidential information in a shared URL.
Information saved in your browser
When browser storage is available, the site may keep display preferences, recent results, favorites, tool input state, and interface choices such as open or collapsed sections. Power station plans are stored only when you choose Save. This information remains in that browser profile unless you delete or clear it; it is not a cloud-synchronized copy.
Imported and exported plan files
Exporting a power station plan creates a JSON file for your browser to download. Importing reads and validates the JSON file you deliberately select. These file operations happen in the browser; Tollica does not upload the plan file to a separate storage service. A downloaded file is outside Tollica's browser storage, so you control where it is kept, shared, or deleted.
Hosting and request logs
Tollica is hosted by Vercel. Like other web hosts, Vercel may process ordinary request information such as the requested URL, date and time, IP address, user agent, and operational or security logs. Vercel describes its handling of this information in its privacy policy.
Analytics, advertising, and monitoring
The site uses Vercel Web Analytics to understand aggregate page visits and general usage patterns, and Vercel Speed Insights to measure real-world loading, responsiveness, and visual stability. Vercel describes these services as using anonymized data without cookies. The application does not include advertising cookies or pixels, or a third-party error-monitoring service.
External links and sharing
References and sharing destinations open only after you choose them. Those sites apply their own privacy policies. The Share action uses ordinary links and does not load social-network software, tracking pixels, or advertising code on Tollica.
Clearing saved information
You can clear favorites and recent items in the tool where they appear, and delete saved power plans from the Saved plans panel. To remove all saved preferences, tool state, and plans at once, clear site data for tollica.com in your browser settings. Clearing site data does not delete downloaded files or copies of links and files you shared elsewhere.
