PRIVACY & LIMITATIONS
Camera settings stay local. No camera is accessed.
Frame rate, light pulse frequency, shutter angle, and tolerance are used only for mathematical enumeration on the current page. FlickerSafe requests no camera or microphone access, reads no footage, and controls no fixtures.
Cycle-alignment guidance, not flicker certification
The tool converts exposure time into light cycles and enumerates up to 200 whole cycles within the maximum shutter angle, showing the 20 closest to the target. The 50/60 Hz shortcuts assume full-wave rectification at 100/120 Hz. Mains frequency does not describe every LED, PWM driver, dimmer, neon lamp, display, multi-phase supply, or failing fixture; rolling shutter, scan direction, sensor readout, and camera rounding can still create bands.
Test sheets may reveal production settings
Refreshing or closing discards inputs. CSV contains frame rate, pulse frequency, exposure, shutter angle, equivalent shutter, and cycle count; reports and optional local checkpoints read the visible summary. Before production, record test footage with the exact fixture, level, dimming state, camera position, and camera.
Advertising and local preferences
This page uses Google AdSense Auto Ads. Google may use cookies or similar technologies under its policies. .miluland.com domain cookies sync language, theme, high contrast, a six-item recent-tools list, and up to 16 favorite tool IDs across MiluLand sites. These values never contain inputs, files, or results; the current site also keeps a local compatibility copy.
← Back to toolLocal report studio
The report studio reads only the workbench’s currently visible result summary for local preview, Markdown copy, JSON download, printing, and a SHA-256 fingerprint. It never reads input controls or original files and is not persisted unless you choose to download it.
Optional local checkpoints
Only when you explicitly choose Save does the tool write the visible result summary, time, and optional short label to this site’s browser storage, up to five entries. Imported files and input-control contents are never stored; you can export, restore same-tool checkpoints, or clear them at any time. Imports are limited to 128KB and validate the tool, timestamp, summary, and label of up to 80 characters.
Analytics and your choices
Google Analytics measures page visits and tool openings. Visitors in the EEA, UK, Switzerland, mainland China, Canada, South Korea, and Türkiye are asked first; other identified regions start automatically. A previous refusal, GPC, or Do Not Track takes precedence. Tools work with either choice.
We use same-site Cloudflare connection information to determine the country or region, not your language, and do not save the IP address in the lookup. If the lookup fails, the Google tag still starts with regional consent defaults: analytics cookies in consent-required regions await permission, while Google may receive basic cookieless signals. Automatic startup is not recorded as your explicit consent.
Files, filenames, tool inputs, search terms, URL parameters, fragments, and results are excluded. Page names use fixed paths and referrers contain only the source site. Google processes visit identifiers and technical browser information. Enhanced measurement, Google signals, and ad-personalization measurement are disabled.
Turn analytics on or off through Privacy & analytics in the footer. Explicit choices are shared across enabled pages in a .miluland.com cookie for up to 180 days; automatic startup does not save an accepted choice. Turning it off stops this integration and clears accessible GA cookies. Advertising uses separate consent settings.
