FAQ
Common questions
Everything you need to know about Legal Sparrow Cloud’s free legal tools.
Are these legal tools really free?
Yes — 100% free, forever. No credit card, no signup, no hidden charges. Legal Sparrow Cloud exists to give back to the legal community.
Do I need to create an account to use the tools?
No. Every tool on Legal Sparrow Cloud works directly in your browser. You can start using them right now with zero registration.
How is Legal Sparrow Cloud different from Legal Sparrow (.com)?
Legal Sparrow Cloud offers free general-purpose legal utilities — calculators, generators, lookups, and templates. Legal Sparrow is our premium AI suite built for deep legal research, document analysis, and drafting at scale. Think of Cloud as the toolbox; Legal Sparrow .com as the full workshop.
Are these tools jurisdiction-specific?
Many of our tools support multiple jurisdictions and let you select yours before generating results. Always verify outputs against your local rules — these tools assist, but don’t replace professional legal judgment.
Is my data safe when I use these tools?
Absolutely. We use a privacy-first design — your inputs are processed in your browser session and never stored, shared, or used for training. No logs, no profiles, no tracking.
Can I use the output in actual legal practice?
Yes, our tools produce professional-grade output meant to assist qualified lawyers. However, every output should be reviewed and adapted to your case’s specific facts and jurisdiction. Legal Sparrow Cloud is a productivity assistant, not a substitute for legal advice.
How often are the tools updated?
We continuously update tools to reflect changes in statutes, court fees, limitation periods, and procedural rules. If you spot an outdated reference, please let us know.
Can I suggest a new tool?
Please do. The fastest way to get a tool built is to request it — fill out the form above and tell us what your practice needs. Frequently requested tools are prioritized and released free.
