Privacy
Seamply is an iPad app with no Seamply account and no advertising, and it does not track you. It needs a connection only to download the pattern of the day, to send a pattern or a report if you choose to, and to send anonymous usage statistics, which you can turn off. Your artwork stays on your iPad unless you submit it. This policy says exactly what leaves your iPad, and why.
Publisher and data controller
Seamply is published by Rémy Boiré, sole trader (entreprise individuelle), registered under SIRET 79792605200060; publication director: Rémy Boiré. The data controller is the publisher, who can be reached at contact@seamply.app. This website is hosted by Vercel Inc., 440 N Barranca Ave #4133, Walnut, CA 91789, USA.
Your artwork
Images you open, paste or edit stay on your iPad. They are processed on the device and stored only in the app’s own storage, so that your last image opens again at launch. Nothing is uploaded unless you submit a pattern (see below); the usage statistics describe an image, they never contain it. When you use Send, iPadOS hands the file to the app you choose through the standard share sheet; where it goes from there is up to you and that app. Deleting the app removes the stored image, your settings and the downloaded patterns of the day from your iPad.
The pattern of the day
When you open the app, and when you come back to it, Seamply downloads the pattern of the day and the next ones from CloudKit, Apple’s cloud service. This needs no account. As with any connection, Apple sees your device’s IP address and, if you are signed in to iCloud, your iCloud account. If you are signed in, CloudKit may also create an identifier for your account that only exists for Seamply. It is not your Apple Account, your name or your email, and it does not tell us who you are.
If you submit a pattern
Submitting is optional and uses the iCloud account signed in on your iPad. When you tap Submit, the app sends:
- your tile, offset and flattened, as an image of at most 4096 pixels per side. Never the PSD, never your layers;
- its repeat layout (grid, half-drop or brick) and its size in pixels;
- the credit you typed: an Instagram @handle or a name;
- your message, if you wrote one;
- the version of the rights text you agreed to.
CloudKit adds the date and your Seamply identifier. Only you and the developer can access your submission. Your message is for the developer only: it helps write the Instagram post, or tells us how to reach you. The developer reviews every submission by hand. If yours is picked, the image and your credit are shown in the app to everyone who opens Seamply, and may appear on seamply.app and on Seamply’s Instagram. An @handle credit links to your Instagram profile.
If you report a pattern
Report sends the pattern’s identifier and the reason you picked. CloudKit adds the date and your Seamply identifier. Reporting needs an iCloud account. Only the developer reads reports.
Why we use it
We use what you submit only to review your pattern and, if it is picked, to feature it with your credit. Featuring it on Instagram and seamply.app also helps make Seamply known. The legal basis is the agreement you make when you tick the box and submit (see the Terms). You can end it at any time by writing to us. Reports are used only to check the reported pattern, on the basis of our legitimate interest in keeping the app safe. Nothing is sold, and nothing is used to train AI.
Who stores it, and for how long
Submissions and reports are stored in CloudKit by Apple Inc., which handles them for us under Apple’s privacy policy. When a pattern is featured on seamply.app, the site’s server reads it from CloudKit and Vercel serves it, like the rest of the site. To schedule its Instagram post, Cloudflare, Inc. keeps the image, the credit and the text of the post until it goes out, then deletes them within 30 days, under Cloudflare’s privacy policy. When it is posted on Instagram, Meta receives the image and the credit, under Instagram’s own terms and privacy policy. We share your submissions and reports with no one else.
Submissions, including those that were not picked or were taken down, are kept as long as Seamply runs the pattern of the day, or until you ask us to delete them. Reports follow the same rule. To have your submissions deleted, write to contact@seamply.app and tell us the credit you used, so we can find them.
Anonymous usage statistics
To see which features are used and to fix what breaks, the app sends anonymous usage statistics to PostHog, hosted in the European Union (Frankfurt, Germany). They cover:
- which features are used: images opened and how they came in, tabs, repeat layouts, sends, exports and copies, the export format chosen, the pattern of the day (its launch screen, its card, submitting and reporting), how long a session lasts and how many gestures it has;
- errors and crashes, including a failed download of the pattern of the day;
- a few performance measurements: how long decoding and exporting take, memory use, and Apple’s daily MetricKit report.
About an image, they record only its format, dimensions, file size, number of layers and color mode. Never its pixels, its file name, or anything you draw. About the pattern of the day, they record that its card was opened, that a pattern was submitted or reported, the reason picked for a report, whether a message was written and whether the credit is an Instagram handle or a name. Never which pattern, the credit itself or your message.
Events are tied to a random identifier created on your iPad. It is never Apple’s advertising identifier (IDFA), your iCloud account, your Seamply identifier in CloudKit or an email address. It is replaced every year, and erased when you turn the statistics off.
Your IP address is not stored, and no location is worked out from it: location lookup is turned off on every event, and IP addresses are discarded in Seamply’s PostHog project.
There is no screen recording, no automatic capture of your taps, no profile of you and no advertising. Nothing is shared with anyone else or sold. Seamply does not track you across apps or websites (no “tracking” in the sense of Apple’s App Tracking Transparency framework).
The statistics are kept for 12 months at most.
This measurement is strictly limited to how the app is used and whether it works properly. That keeps it within the audience measurement exemption of the CNIL, the French data protection authority, so the app does not ask for consent first. The legal basis is Seamply’s legitimate interest in understanding how the app is used and keeping it working (Article 6(1)(f) of the GDPR). You can turn it off at any time: open Settings on your iPad, tap Seamply, and turn off Share Anonymous Usage Data.
The app works the same without a connection: the statistics wait until the iPad is back online.
Your rights
The usage statistics are tied to a random identifier, never to your name, your email or your Apple account. You can object at any time by turning off Share Anonymous Usage Data: sending stops and the identifier is erased from your iPad. For this website, use the button in the section about it below.
For your submissions and reports, you can ask to see, correct or delete your data at any time, by writing to contact@seamply.app. We do not know who you are, so tell us the credit you used. You may also lodge a complaint with your data protection authority (in France, the CNIL).
This website
The site at seamply.app sets no cookies and stores nothing on your device to count visits. To know how many people visit, which pages they read and how they found the site, each page you open sends a few details to PostHog, in Seamply’s project hosted in the European Union (Frankfurt, Germany):
- the page’s address and title, how long it stayed open, how far down you scrolled, the site that sent you here (its domain only) and any campaign tags in the link;
- your browser’s language and time zone, the size of your screen and window, and the type of device, browser and operating system, read from the browser’s user agent;
- when you tap a link to email us, and where it was on the site;
- in the app demo on the home page, which gestures and controls you use, each counted once per visit and per tab, never where you touched;
- in the free pattern checker, how you opened an image (file, drop, paste or sample), its format, whether it repeats without visible seams and in which layouts, or why it could not be read, and which controls you use. The image itself never leaves your browser: no pixels and no file names are sent.
To tell visitors apart without a cookie, PostHog turns your IP address, your browser’s user agent and the site’s domain into a one-way code, mixed with a random secret that changes every day and is deleted a few days later. The next day, the same visitor gets a new code, so visits cannot be linked from one day to the next. Your IP address and user agent are then discarded: they are not stored, and no location is worked out from them.
There is no screen recording, no automatic capture of your clicks, no profile of you and no advertising. The site’s statistics are never linked to the app’s, nothing is shared with anyone else or sold, and you are not tracked across websites. They are kept for 12 months at most.
Like the app’s statistics, this measurement stays within the CNIL’s audience measurement exemption, so the site does not ask for consent first. The legal basis is Seamply’s legitimate interest in knowing how the site is used (Article 6(1)(f) of the GDPR). If your browser sends Global Privacy Control or Do Not Track, nothing is sent. You can also object here; your choice is kept in this browser only:
As with visiting any web page, Vercel, the site’s host, sees the connection’s IP address; it is not used for measurement or tracking.
The home page shows the pattern of the day. The site’s server reads it, with its credit, from Seamply’s public database in CloudKit, Apple’s cloud service. It sends Apple nothing about you. The image is then served by Vercel from seamply.app, so your browser never connects to Apple.
Beta testing
The beta is distributed through Apple TestFlight. Apple collects your TestFlight participation data and crash reports under Apple’s privacy policy; the developer sees only the aggregate tester and crash information Apple provides. If you email feedback, that email is kept only as long as needed to answer it.
Children
The app is not directed at children. You must be 16 or older to submit a pattern.
