Your data

Your data stays on your device.

Annus Mirabilis has no accounts, no logins, no advertising and no tracking cookies. Your reading preferences, notes, predictions and tour progress are kept in this browser’s own storage, and nowhere else.

Nothing you save is sent

No server receives your notes, settings or predictions. Open your browser’s network panel and read this site: the only things it asks for are its own pages, fonts, figures, and the files an instrument needs when you open one.

Take it with you

“Download all of it” below writes one JSON file named annus-mirabilis-data- and today’s date. It contains every key listed on this page that has anything in it.

Delete it yourself

Clear one kind, or all of it, from the panel below. Either way the site asks you to confirm on the page itself first, and clearing reaches this browser and nothing else.

The names to look for

Everything this site keeps is under a key beginning am: in this browser’s local storage. You do not have to take that on trust: open your browser’s developer tools, find local storage for this site, and compare what is there against this list. Anything under am: that is not named here is a defect, and nothing else on the page can tell you that.

Settings, one short value each

  • am:settings:v1:theme Reading theme
  • am:settings:v1:detail Detail (reading depth)
  • am:settings:v1:perspective Perspective (paper or modern lens)
  • am:settings:v1:notation Notation (printed or modern symbols)
  • am:settings:v1:units Units (historical or modern constants)
  • am:settings:v1:readingOnly Reading-only mode
  • am:settings:v1:measure Line length
  • am:settings:v1:typeScale Type size
  • am:settings:v1:contrast Contrast
  • am:settings:v1:paragraphSpacing Paragraph spacing
  • am:settings:v1:predictEntry How an instrument opens: predict first, an example first, or explore
  • am:settings:v1:glossReasoningWords Gloss reasoning-words toggle

Work you saved

  • am:discovery-notes:v1:light-quanta Discovery notes: Light quanta
  • am:discovery-notes:v1:brownian-motion Discovery notes: Brownian motion
  • am:discovery-notes:v1:special-relativity Discovery notes: Special relativity
  • am:discovery-notes:v1:mass-energy Discovery notes: Mass and energy
  • am:quarantine:v1 Saved data this site could not read, kept aside
  • am:notebook:v1 Notebook
  • am:notebook-recap:v1 The “continue where you left off” line you dismissed
  • am:tours:v1 Progress on guided reading paths
  • am:predictions:v1 Saved predictions
  • am:journeys:v1 Your choices and progress in Discover
  • am:kitchen:v1 Kitchen-mode observations you chose to keep: clicks and calibration, never video
  • am:clarity:v1 Your “this was clear” answers

Every one of them is included in the download and removed by a clear. Reading continues if your browser blocks storage or runs out of room: the site loses your place and your preferences, not the text.

One of these is not built yet

am:clarity:v1 is reserved for a one-click “this was clear / this was not” answer under a paragraph, recording the detail level and the anchor and nothing about you. The key is registered and the control is not written, so as of today nothing writes to it and there is nothing in it to export. It is named here anyway, because a list that quietly left it out would be a list you could not check.

Where to go next

  • About this edition says who made it, what is reviewed and what is not.
  • Accessibility says what has been checked and by what method.
  • The Reading preferences button in the header, beside the theme control, is where most of the settings above are set.
  • Sources shows where the papers themselves come from, which is the other half of what this site asks you to trust.
