Thousands of photos. One story.

Your phone captures everything and remembers none of it. In Yesterling every moment becomes an entry: the photos, the date, the place and whoever was there.

A timeline in the app: monthly photos with the child’s age on each.
Timeline · example

  • Memories, milestones, activities

    Up to 50 photos and videos in a single entry, with a title, notes, the date, the place and the people who were there.

  • Timelines

    One photo a week or a month, with your child’s age that day under every frame. A year of growing up in a single scroll.

  • Gallery

    Every photo and video in the order it was taken. Each one tells you which entry it belongs to.

  • People and places

    Grandad, an aunt, a friend from nursery: add people in your own words, and nobody gets a notification or an invite. “Every moment with Grandad” is one search away.

Height, weight, percentile.

Add a measurement and see it on international growth curves. Measurements don’t count towards your storage.

  • World Health Organization (WHO) growth curves for 0–24 months, the US CDC’s from age 2
  • Weight and height, plus body mass index from age 2
  • A target-height estimate from both parents’ heights
  • kg or lb, cm or inches: whichever you’re used to
50 60 70 80 90 0 6 12 18 24 months cm P3 P15 P50 P85 P97
Example measurement Curves drawn from the official tables the World Health Organization publishes (3rd, 15th, 50th, 85th and 97th percentile). The dots are example measurements.

The original. Not a compressed copy.

We keep the photo you upload from your phone exactly as it is, untouched. We never shrink a photo, and you can download the original whenever you like.

  • The JPEG, PNG and HEIC photos that phones take are kept unchanged.
  • No photo is ever shrunk.
  • For the rare file types whose original we can’t keep, the entry says so plainly.
  • The location and device details your phone adds to a photo by itself are removed from the copies shown in the app.

File and folder names come from the package the app builds today. The photo and video names are examples.

No ads. On any plan.

Nothing tracks you for advertising, either. Statistics on how the app is used are only collected if you say yes. Notifications never mention your child’s name.

This page isn’t watching you either.

This page connects to no other website and leaves no cookies.

Who sees what

Who What they see
You Everything.
Our support team Account details and whatever you send us yourself. They have no screen that shows your archive.
The servers your data is stored on Your entries and photos are stored here. The privacy policy says where they are stored.
Google (place search) The words you type into the search box when adding a place to an entry. Your phone doesn’t connect to Google directly. Only the place you choose is saved to the entry.
Apple and Google (payment) Your subscription purchase. Your card details never reach us.
Crash reports Sentry If the app crashes or hits an error, a technical record of what broke. It never contains your name, email, photos or notes. On by default. One tap turns it off.
Usage statistics PostHog Numbers about how the app is used. Collected only if you say yes.
Ad networks None.

Privacy policy (draft)

Delete means delete.

When you delete your account you have 30 days to change your mind, and we remind you with seven days to go. When the time is up, your photos, entries and payment history are deleted.

  1. Day 0 Deletion request. Your account becomes view-only. Your archive stays as it is.
  2. Day 23 Warning email: seven days left.
  3. Day 30 Photos, entries and payment history are deleted.

You can change your mind at any point in those 30 days.

What if I can’t log in for a long time?

We let you know by email. Your archive stays as it is. Nothing is deleted just because you haven’t logged in for a long time. Only you can close your account.

A child’s profile with entries isn’t deleted but archived, so it can’t vanish by accident.

Start free with 5 GB.

It comes with your account. Only photos and videos take up space. Your notes and measurements don’t.

Free

5 GB

≈ 600 photos

No ads, full archive download included. No payment details needed to start.

When you need more room

  • 50 GB ≈ 6,000 photos
  • 200 GB ≈ 24,000 photos
  • 400 GB ≈ 48,000 photos
  • 800 GB ≈ 96,000 photos

Monthly or yearly. You pay through the App Store or Google Play, in your own currency.

Prices will be in the App Store and Google Play at launch.

Photo counts are rough: originals are kept, so it depends on the size of your files.

The questions you’re asking, answered straight.

We don’t promise what we can’t say yes to. “Not yet” is an answer too.

Can my partner or my child’s grandmother see it too?

Not yet. Today Yesterling is one person’s archive. The way to share is the export. It isn’t a substitute for sharing.

Is it end-to-end encrypted?

No. Search and small previews are prepared on our systems, so our systems need to be able to open the photos. What we do instead: your photos never sit at a public address, and each time one opens, a link is created that only works for a short while. Your archive is kept in a section set aside for your account alone at the system level. Our support team has no screen that shows your archive.

Can I upload older photos from my phone?

Yes. Every entry has its own date. The photo’s capture date is suggested, and you can change it. You can’t bring over your whole camera roll in one go. You create entries one at a time.

Do my iPhone photos (HEIC) work properly?

Yes. A copy is prepared on your phone for showing in the app. The original file your iPhone took is kept completely unchanged and returned to you whenever you ask.

How do I download, and is there a limit?

From the app or from your computer. One package is prepared at a time. You can ask for a new one 24 hours after a package is ready. A package stays downloadable for 7 days. Free, on every plan.

What happens if my subscription ends?

Only new uploads stop. Viewing, editing, deleting and downloading stay open. A billing problem never locks anything.

Which languages?

Turkish, English, Spanish. Search doesn’t trip over accents or special letters: type “e” instead of “é”, or “s” instead of “ş”, and it still finds it.

Can I use it on the web?

No. The app is on iOS and Android. You can download the export package to your computer.
