Version of 19 October 2026. Changes are posted on this page.

Hirsla Privacy

Hirsla has no account, no analytics, and no server of mine. Your cards live on your iPhone or iPad and, if sync is on, in your own iCloud. I cannot see them.

That is the short version. Because “nothing ever leaves your phone” is the kind of claim that is easy to make and rarely true, the rest of this page lists everything that does leave, and why.

01

What stays on your iPhone or iPad

Your cards, their text, their summaries, and the facts read out of them. Photos, PDFs, files, and recordings you save. Your own notes. The search index.

The reading happens there too. Titles, summaries, tags, facts, transcription of voice memos, reading handwriting, search and Ask all run on your iPhone or iPad, on Apple’s on-device models. Nothing is sent anywhere to be read, and no part of your library is used to train anything.

02

What leaves your iPhone or iPad

Five things, and nothing else.

Saving a link loads that page. When you share a link into Hirsla, your device fetches it from whichever server it lives on, to read its title, description, and preview image. That server sees the request, as it would in any browser. It does not come to me. A YouTube or Vimeo link is read through that service’s own preview service instead, for its title, channel, and thumbnail, which come from that service’s servers. A link’s preview is loaded again if its saved image is gone, and saved links are read again after an update that improves how they are read.

Places are looked up in Apple Maps. Saving a place, and showing a card on the map, asks Apple Maps for the name and address. A Google Maps link is opened once at Google, to find out which place it is. When Apple Maps knows a place’s own website, that website is loaded once, so the card can be found by what is on it. If you switch on “Save where I capture”, the place where you saved something is turned into an address the same way. This is Apple’s service, under Apple’s privacy terms.

iCloud sync goes through your own iCloud. Sync is on by default and can be switched off in Settings. When it is on, your cards and their originals travel through your personal iCloud account, in a private database only your Apple ID can open. It is Apple’s infrastructure, not mine, and I have no access to it.

Purchases go through Apple. Card packs are bought with Apple’s in-app purchase system. Apple handles the payment and tells the app that a purchase exists. I never see your name, your payment details, or your Apple ID. I see sales totals in App Store Connect, the same as any developer.

A problem report you choose to send. If you use Report a problem, your mail app opens with a diagnostics report and recent app logs attached, and you send it to me. Together with feedback you choose to send, that is the only way anything from the app reaches me, and it only happens when you decide to send it. You can read the attachment first, and remove it.

Nothing goes to me, and nothing goes to an AI company, unless you choose to send feedback or a problem report.

03

Permissions the app asks for

Photos, when you pick a photo or video to save. Camera and microphone, when you take a photo, scan a document or record a voice memo. Speech recognition, to turn a recording into text on the device. Location, only if you switch on “Save where I capture”, and only to note where a card was saved.

Each one is asked for at the moment you first use the feature, and the app works without any of them.

04

Keeping and deleting

Cards stay until you delete them. A deleted card sits in Recently deleted for 30 days, where you can put it back, then it is removed for good from your devices and from iCloud.

Deleting the app removes the library on that device. If sync was on, the copy in your iCloud stays until you remove it from iCloud settings.

Backups are copies of your own library kept on your own iPhone or iPad, and in its iCloud Backup if that is on. They are not sent to me.

05

Your rights, and why they are easy here

There is no account to close and no profile of you to hand over, because I hold nothing. Your data is already in your possession: Export everything writes the lot to a zip file: a folder of Markdown files with the original files beside them, and that is never locked behind a purchase.

If you have sent me a problem report and want it deleted from my mailbox, write to me and I will delete it.

Swiss and European data protection law gives you rights of access, correction, and deletion. For anything I actually hold, which is email you have sent me, those rights are a single message away.

Children

Hirsla is a general-purpose app and is not directed at children. It does not knowingly collect anything from anyone, of any age.

Who is responsible, and how to reach me

Hirsla is a private side project and has nothing to do with my employer.

Niklaus GerberDigital & Platform Executive

Twenty years making digital stick in organisations not built for it.

Vice President Digital at Vorwerk Home, responsible for product, platform, and e-commerce across Europe. Before that, I founded the product function at NZZ.

My work sits where digital ambition meets legacy platforms, many stakeholders, and teams that need a reason to change. At NZZ, we shipped AI audio in 2018, among the first publishers anywhere to do so.

Playground

I build tools when the thinking needs a shape. Lately that means hands-on work with agentic AI. Most start as a fix for my own team and then find a wider audience. Each one tests an idea before I put more weight on it.
