Two questions come up before anyone commits to a Angle Converter: is it safe to paste real work into, and is the free version enough or do you need to pay? This guide answers both directly, without marketing language.
Is It Safe to Use?
Safety comes down to what happens to your input. Before you paste anything real, open the privacy information and look for three answers: is input stored, is it used to improve the service, and for how long. Anything you cannot find documented should be treated as unknown. The practical rule: paste material you would be comfortable seeing in a support ticket, and keep the rest out.
What You Should Never Paste
- Passwords, API keys, tokens or any credential, even test ones.
- Personal data about other people - addresses, health or financial details.
- Unreleased documents covered by confidentiality obligations.
- Client data your own agreements forbid you from sharing with third parties.
- Anything you would not want indexed, logged or quoted back at you.
What the Free Version Covers
Unlimited conversions, all three angle units, exact pi maths and no sign-up.
For occasional and weekly use this is genuinely enough - most people never need more.
What Paid Plans Add
This tool is free.
These matter when the tool is part of daily production rather than an occasional helper.
Free vs Paid: How to Decide
- Use the free version on real work for seven days, not test prompts.
- Note every moment you wished for a paid feature.
- Price the paid plan against the hours it would actually save.
- If the wish list stays short, stay free; if it grows weekly, upgrade for a month and re-check.
A 60-Second Safety Checklist
- No credentials or personal data in the input.
- Privacy terms read for storage, training and retention.
- Output reviewed for facts before anything customer-facing ships.
- Free tier tested against your real weekly volume.
Frequently Asked Questions
Which angle units are supported?
Degrees, radians and gradians, the three standard ways to measure a turn.
How many radians are in 180 degrees?
Exactly pi radians, about 3.14159 - a full circle is 2 pi radians or 400 gradians.
What are gradians used for?
Surveying and some engineering drawing work - a right angle is 100 grad instead of 90 degrees.
Is my input stored?
No - everything runs in your browser.
