A DUE-Sh.D — Couple Calendar

A couple calendar that keeps your story on your phone — pair, and only ciphertext ever leaves it.

• Enter the day you met — 100-day marks, day 1000, anniversaries, all automatic
• Valentine's, White Day and friends, handled
• Alerts 7/3/1 days before and on the morning of
• Home & Lock Screen widgets — day count and next D-day, always in sight
• Add your own days (lunar-calendar repeats supported)
• Our plans — upcoming dates and trips as D-days, with their own widget
• Bucket list — things to do together, kept with the day you did them
• Date roulette — can't decide? Draw a card and it becomes a plan
• Love language — a five-question quiz, each other's language on both screens
• Our story — a timeline of every milestone you've passed together
• Couple card — export your D-day as a 9:16 card for stories (free)
• Your couple photo as the home and widget background · every theme free

Pairing (optional): one code keeps both phones in step. Everything is
encrypted on-device before relay — without the code, no one (including us)
can read it. Skip pairing and none of your entries ever leave the phone —
the app only fetches a single status file when it opens. Photo originals
stay on each phone; photos in memories and plans pass as encrypted copies,
and the server keeps at most 400 per couple before clearing the oldest.

Signal pack (one-time): a "miss you" heart lands right on your partner's
home-screen widget — no need to open the app. Signals like Miss you, Good
night, Kiss and You got this, plus a mood you can hang on their widget for
24 hours. Long-press a signal notification to reply in place, send from
the Lock Screen or Control Center button, or send right from Apple
Watch — and every heart is kept in a little chronicle. Receiving is free,
so one purchase unlocks sending for both of you — and it includes every
paid feature to come. Signals are encrypted too.

No account, no sign-in, no ads, no subscriptions — everything else is
free. Even if you part ways, or this app disappears, your records stay
on your phone.
