Privacy Policy

Summary

• Haku sees the videos you allow. When you add videos from Photos, Haku may ask to see your photo library, and you choose all of it, some videos or none. It never changes your library, and only the videos you add are uploaded.
• Your originals are never changed. Edits point to parts of your videos; they don't rewrite them.
• We don't sell your data and don't show ads. We never share your videos or data with anyone for their own purposes. The companies that run parts of Haku for us may use them only to do that work.
• We use your content only to provide Haku to you. If we ever want to use it for anything else, we'll ask you first, and you can say no.
• Haku counts and frames people; today it doesn't recognize who they are. It doesn't create or store face templates. If that changes, we'll tell you first, as described under Changes.
• You can ask us to see, correct, export or delete your data at any time by writing to privacy@hakustudio.art.

Who we are

Haku Studio (“Haku”, “we”, “us”) makes the Haku Studio apps for iPhone, iPad, Mac and Apple Watch, and this website, hakustudio.art. We are responsible for the personal data described here.

We follow the data-protection laws of the countries where we operate and where the people who use Haku live, including Mexico's Federal Law on the Protection of Personal Data Held by Private Parties (LFPDPPP) and your ARCO rights under it. Where another law gives you more protection, we apply it.

Haku is in private beta. While it is, this policy describes the app as it works in the beta and as its features arrive. We'll update it as Haku changes.

What the website collects

• The contact and beta form. Your name, email, topic, message and, if you ask to join the beta, what you make, your devices and cameras, how often you post and where. The form is handled by Formspree, which sends it to our inbox.
• Emails you send us. Whatever you choose to write, kept in our email service.
• Basic technical data. Amazon Web Services, which delivers this site through Amazon CloudFront, receives your IP address and browser details to deliver the site and protect it from abuse. We don't keep access logs.

The website uses no cookies, no analytics and no trackers. Your language choice is remembered in your browser's own storage and never sent to us. Fonts and images are served from our own site.

What the app collects

Your account

You sign in with Apple or with Google. We receive an identifier for your account from them, not your name or email address, and we don't ask for either. We store that identifier, your language and when your account was created. Accounts made with Apple and with Google are separate.

Your videos

Only the videos you add to a Collection. Haku keeps a copy of each original, plus a smaller preview copy and a thumbnail it makes from it. It also keeps each file's technical details: its name, size, format, a checksum, and camera information such as make, model, recording date and time zone. It doesn't keep camera serial numbers.

Location is used only if you allow it, and is reduced to a city or to whether clips were recorded in the same place. AI models never receive exact coordinates.

What Haku learns from your videos

To find the good moments, Haku analyzes the videos you picked: what was said (as text with timing), scenes and shots, motion, image quality, sounds and music, text that appears on screen, and the objects and settings in view.

For people, Haku notes how many are in a shot, how they're framed and whether a face is visible. Today it doesn't recognize or identify anyone, and it doesn't create or store face templates or anything that could identify a person by their face or body. If that changes, we'll tell you before it applies and ask for your permission when the law requires it.

What you tell Haku

The notes you add (stored as text, never as audio, including notes dictated on Apple Watch), your description of the video you want, your answers to Haku's questions, and your edits and versions, with their history so you can undo.

Your preferences

As you keep, change or drop what Haku suggests, Haku can remember simple patterns, such as the kinds of shots you usually keep, so your next cut fits you better. These are stored as codes and counts only: never your words, notes, transcripts, frames, faces or location. You'll be able to see, reset or turn this off in the app, and it's deleted with your account.

Technical information

App version, device type, operating system and language, and error details we need to fix problems. These never include your videos, file names, titles, what you type, or your location.

Your choices

Records of the choices you make in Haku about your data, such as permissions you give or withdraw, so we can respect them.

How we use it

• To provide Haku: store your videos, analyze them, build and change your cuts, export them and share the versions you choose.
• To keep Haku secure and reliable: prevent abuse, fix errors and enforce the beta's limits.
• To talk with you: answer messages, invite you to the beta and tell you about important changes.
• To comply with the law.

We don't sell your data, don't use it for advertising and don't build advertising profiles. We use your videos and what Haku learns from them only to provide Haku to you. If we ever want to use them for another purpose, we'll ask for your permission first, separately, and you can say no or change your mind later.

How Haku makes a cut

Speech is turned into text by software we run on our own servers, so no outside service receives your audio for that.

To choose and order the moments for your cut, Haku sends a text summary of your footage to AI models that run on Amazon Bedrock, a service of Amazon Web Services (AWS): what was said, the labels from the analysis, your notes and your description. Haku doesn't send your video frames or audio to these models. AWS processes these requests only to return the result to us, may process them in AWS regions outside Mexico, and some models keep requests for up to 30 days for abuse monitoring before deleting them.

Haku only gives a model information from the Collection you're working on, never from your other Collections.

Who processes it

We never share your data with anyone for their own purposes. These providers process it on our behalf, only to do their part of running Haku:

We also share data when you ask us to: a private link lets anyone who has it watch the one version you shared, until you turn it off. And we may disclose data when the law requires it, to protect people's safety or rights, or as part of a merger or sale of Haku Studio, in which case this policy keeps applying to your data.

Where it's stored

During the beta, your account, videos and edits are stored with AWS in Mexico. Some providers above, and Amazon Bedrock's processing, may be in the United States or other countries. When data moves between countries, we use providers bound by contract to protect it as this policy does.

How long we keep it

Deleted data can stay in encrypted backups for a short time until those backups expire.

Security

• Connections are encrypted (TLS), and stored videos and databases are encrypted at rest.
• Your videos are kept in private storage. The app gets short-lived links to play them.
• Every request is checked against who owns the account, the Collection and the video.
• Our team's access is limited to what each task needs, and our logs leave out your videos, descriptions, transcripts and links.

No system is perfectly secure. If a breach affects your data, we'll tell you and the authorities as the law requires.

Your rights

You can ask us to:

• Access the personal data we hold about you, and get a copy you can take elsewhere.
• Correct it if it's wrong.
• Delete it, or your whole account.
• Object to or limit a use of it, and withdraw a permission you gave.

During the beta, write to privacy@hakustudio.art from the email you used with us, or tell us which sign-in you use, so we can confirm it's you. We answer within 20 business days. Deleting your account from inside the app is coming before Haku opens beyond the private beta. You can also complain to the data-protection authority where you live.

Age

Haku is for people 18 or older (or the age of majority where you live). We don't knowingly collect data from children. If you believe a child has given us data, write to us and we'll delete it.

Changes

When this policy changes, we'll update the date at the top. If a change is important, we'll tell you in the app or by email before it applies, and ask for your permission when the law requires it.
