Frequently Asked Questions

What are the working of the Browser-based tools?

All the tools in the OneShotSEO suite are based on client-side APIs, standard HTML5 Canvas and state-of-the-art JavaScript engines. All computation jobs are done in the memory processor of your device, not transferring files to remote servers when loading a video, image or raw code formatting snippet.

Will my information be protected and remain confidential?

Absolutely. Your raw data never leaves your browser window as all converters, calculators and builders are performed locally. It works best when it comes to data security and is ideal for corporate employees who are under strict regulations.

Are there any day to day restrictions?

No. There are no payment walls, daily payment limits or email sign up requirements. Create, optimize and purify documents as many times as desired without any hassle.
