What this page does not claim
- It does not claim Grand Print is faster; no controlled cross-product benchmark supports that.
- It does not claim every competitor uploads images; several reviewed tools document local processing.
- It does not treat “private,” “free,” or “no watermark” as equivalent across separate domains.
- It does not copy another product's branding, wording, interface, code, or assets.
