Privacy Policy
This policy explains what Elemora: Periodic Table does with information, in plain language. It applies to the Elemora iOS application and to this website.
The short version
Elemora has no account and no sign-in. Your favourites, saved compounds, study history, streak and mastery are stored on your iPhone by the app. Idlery Services LLC does not run a server that holds your studying, does not build a profile of you, and does not sell or share your information. Deleting Elemora removes what it stored, along with the app. The one thing Elemora sends out on its own is a compound name or formula to PubChem, the public chemistry database, when you look a compound up that is not already on your device.
The rest of this page is the detail behind that paragraph, including the part Apple plays when you buy a subscription.
No account, no sign-in
There is nothing to register for. Elemora never asks for your name, your email address, a password, a phone number or a date of birth, and there is no “sign in with” button anywhere in the app. Because there is no account, there is no account record for us to hold, lose or hand to anyone.
What Elemora stores on your device
Elemora keeps your work so it is still there the next time you open the app. All of it is written into Elemora's own storage on your device — the app container that iOS gives every app and keeps separate from other apps:
- Favourites
- The elements and compounds you have marked with the heart.
- Saved compounds
- Compounds you built in the Build tab and chose to save.
- Study history
- Which cards you answered, how you marked them, and how accurate you have been recently.
- Mastery and progress
- Which elements you have started, which you have mastered, how many compounds you have studied, and the rank those add up to.
- Streak and daily challenge
- The dates you studied, so the streak counter and the daily challenge know where they stand.
- Settings
- The preferences you set in the app.
- Purchase status
- A local note of whether a subscription is currently active, so Elemora knows what to unlock without asking Apple on every screen. See Subscriptions and Apple.
None of this is transmitted to Idlery Services LLC. It is not a copy of something we hold elsewhere — the device is where it lives.
The chemistry data inside Elemora
The element data, the written explanations, the structure diagrams and the compound catalogue that Elemora matches your builds against are part of the app itself: they are installed with it and read from your device. Every one of the 118 elements is bundled, so browsing the table, opening an element and studying make no network request of any kind, and none of it requires an account.
Compounds are the exception: the catalogue inside the app is a selection, not all of chemistry, so a compound it does not have is looked up at PubChem. That is described in the next section.
Elemora is an educational reference. It is not a laboratory instrument, a safety authority or a source of medical or professional advice — see the Terms of Use on how far its data should be relied on.
Compound lookups and PubChem
The Build tab and the compound half of search can ask PubChem — the public chemistry database run by the U.S. National Library of Medicine — for a compound Elemora does not have bundled. This is the only outbound connection Elemora makes on its own.
- What is sent
- The compound name you typed, the formula you assembled in the builder, or a PubChem compound identifier when a record is opened. Nothing else: no name for you, no identifier for you or your device, no progress, no favourites and no history.
- When
- Only when you search for a compound or look one up, after you have stopped typing or changing the formula, and only if nothing already on your device answers it. Elements, the table and studying never cause a request.
- How
- A plain HTTPS request straight to PubChem's public service. There is no API key, and no server of ours in between — Idlery Services LLC does not see these lookups at all.
- What comes back
- Cached on your device so the compound keeps working offline afterwards. It is never sent anywhere else.
- Offline
- Bundled and previously fetched compounds keep working, and Elemora says when it cannot reach PubChem rather than pretending a lookup found nothing.
What PubChem does with the requests it receives is covered by the NIH's own privacy policy at nlm.nih.gov, not by this one. Elemora shows “Data source: PubChem” and the compound identifier on every record that came from it.
Camera
Elemora includes a feature that uses your device's camera. iOS asks for your permission the first time it is used, and you can change your answer at any time in the Settings app under Privacy & Security → Camera, or under Elemora's own entry in Settings. If you decline, the rest of the app carries on working normally.
What the camera sees is used on your device for that feature while it is on screen. Camera frames are analysed on your device by iOS itself; Elemora keeps no image, writes none to disk and uploads none anywhere, and it does not add anything to a photo library on its own. The only thing that can leave the device is the text that was recognised — a chemical name, a formula or a structure identifier — and only when neither the bundled catalogue nor your device's cache already answers it, in which case it goes to PubChem exactly like a typed search. An element never leaves the device at all: all 118 are bundled. Elemora never asks for your location, your contacts, your microphone, your health data or your calendar, and it does not request photo library access.
Sharing a quiz
A quiz you have saved can be shared from My Quizzes → Share. It becomes an ordinary https link under https://elemora.idlery.com/quiz/…, which you send yourself through Messages, Mail, AirDrop or anything else you choose.
The quiz travels inside the link. Its name and its settings — what it draws from, how many questions, and the question types — are compressed and encoded into the address itself. Nothing is uploaded, there is no Elemora account and no quiz database, and there is nothing on a server for us to keep or delete. When someone opens the link with Elemora installed, the app decodes it, checks it and saves the quiz on their device. When they open it without Elemora, they get an ordinary page on this website that says a quiz was shared; the page never decodes or displays the quiz, and the quiz is not sent to us.
What is not in the link: no progress, no favourites, no study history, no scores, no name, and no identifier of the sender or their device.
Encoded is not encrypted. A shared quiz link is a normal web address, so treat it like one. Anyone who receives or forwards the message can open it, and it can appear in browser history, in the records of the services that carry the message, and in the link-preview fetches those services make. If you would not want a quiz seen by whoever the message might reach, do not share it as a link.
Requests for /quiz/ pages on this website are sent with no referrer, are not stored in shared caches and are not offered to search engines. Like the rest of the site, the page runs no scripts and loads nothing from a third party, so the encoded quiz is not passed to any analytics or tracking service.
What leaves your device
Four things can cause information to leave your iPhone, and every one of them is something you start:
- Looking up a compound. A compound name or formula goes to PubChem, as described under Compound lookups and PubChem.
- Sharing a quiz. The quiz goes wherever you send the link, as described under Sharing a quiz.
- Buying or restoring a subscription. That is a conversation between your device and Apple. It is described below.
- Emailing us. If you write to support@idlery.com, we receive whatever you put in the message — your email address, and anything you attach, such as a screenshot. We use it to answer you and to fix what you reported, we keep it only as long as that takes plus a reasonable period for our records, and we do not add you to a marketing list.
Elemora does not send your favourites, saved compounds, study history, mastery, streak or settings anywhere, and none of them is included in a shared quiz link.
Subscriptions and Apple
If Elemora offers a paid subscription, it is sold as an auto-renewable In-App Purchase through the App Store. Apple processes the payment. Your card details, billing address and Apple Account credentials go to Apple, never to us. Idlery Services LLC does not see, receive or store your payment information.
What Elemora learns from that transaction is limited to your entitlement — in effect, whether a subscription is currently active and until when — which it keeps on your device so it knows what to unlock. Elemora does not operate a receipt-validation server of its own.
Apple's own handling of your purchase is governed by Apple's Privacy Policy and the Apple Media Services Terms and Conditions, not by this policy. Apple may provide us with aggregated, anonymous sales and usage reports through App Store Connect; those reports are statistics about the app, and they do not identify individual users to us.
Analytics, tracking and advertising
Elemora contains no advertising, no advertising identifier, and no cross-app or cross-site tracking. It does not ask for App Tracking Transparency permission, because there is nothing in the app that would justify asking. It does not build an advertising or marketing profile of you, and it does not sell or share personal information — including within the meaning given to “sale” and “sharing” under California law. There is no analytics, attribution or crash-reporting SDK inside Elemora at all: the only network requests it makes are the PubChem lookups above.
Crashes and diagnostics
If you have turned on Share iPhone Analytics and Share with App Developers in the Settings app, Apple may share crash and performance data for Elemora with us through App Store Connect. That is Apple's mechanism, not ours: the reports are about the software, they reach us in aggregate, and they do not tell us who you are. You can turn it off at any time in Settings → Privacy & Security → Analytics & Improvements.
Third parties
Two third parties are involved in the normal use of Elemora. Apple distributes the app and processes any purchase, in the two roles described above. PubChem, run by the U.S. National Library of Medicine, answers compound lookups, as described under Compound lookups and PubChem. Beyond those two, Idlery Services LLC does not pass your information to advertisers, data brokers, analytics vendors or anyone else — and neither of them receives anything that identifies you.
We may disclose information if the law requires it — a valid subpoena, court order or comparable legal obligation — or to protect our rights or someone's safety. In practice there is very little to disclose, because your studying is on your device and not with us.
Device backups
If you back up your iPhone to iCloud or to a computer, that backup may include Elemora's stored data along with everything else on the device. That backup belongs to you and is governed by Apple's terms and privacy policy. It is how your favourites and progress can come back when you restore a device — and it is also why setting up a new iPhone without restoring such a backup starts Elemora fresh.
Deleting your information
Because Elemora's records are on your device, you control them directly:
- Remove individual items from inside the app — un-favourite an element, delete a saved compound.
- Look in Elemora's settings — the gear at the top right of the Progress tab — for options to reset progress or clear stored data, if you want to start over without removing the app.
- Delete the app. Removing Elemora from your iPhone deletes its app container, and with it the favourites, saved compounds, study history, mastery, streak and settings stored there. Copies inside a device backup you have already made are not affected; manage those through iCloud or your computer.
Deleting the app does not cancel a subscription. Cancel that through Settings → your name → Subscriptions, as described on the support page.
If you have emailed us and want that correspondence deleted, write to support@idlery.com and we will remove it, subject to any records we are legally required to keep.
Children
Elemora is a general-audience educational app and is not directed to children under 13. It does not knowingly collect personal information from children, and because it has no account, no sign-in and no way to send your studying to us, there is very little for it to collect from anyone. If you believe a child has sent us personal information by email, write to support@idlery.com and we will delete it.
Your rights
Depending on where you live — for example under the GDPR or UK GDPR in Europe and the United Kingdom, or under the CCPA/CPRA in California — you may have the right to ask what personal information we hold about you, to get a copy, to correct it, to delete it, to restrict or object to its use, and not to be discriminated against for asking.
For most people using Elemora the honest answer is that we hold nothing, because the app keeps your studying on your device and sends us nothing. Where we do hold something, it is because you emailed us. Send any request to support@idlery.com and we will respond within 30 days. If you are in the EEA or the UK, you also have the right to complain to your local data protection authority.
Where the GDPR applies, our lawful basis for handling a support email is our legitimate interest in answering you and supporting the app. Idlery Services LLC is based in the United States, so an email you send us is handled there.
This website
elemora.idlery.com is a set of static pages. It sets no cookies, runs no analytics, embeds no tracking pixels, loads no third-party fonts or scripts, and has no sign-up form. Our hosting provider processes standard server request logs — such as IP address and user agent — to deliver the site and keep it secure, as any web host does.
Changes to this policy
If Elemora changes in a way that affects this policy, we will update this page, raise the version number and change the effective date at the top. Material changes will also be noted in the app's App Store release notes. This page at https://elemora.idlery.com/privacy is the canonical, current version.
Who is responsible, and how to get in touch
Elemora: Periodic Table is published by Idlery Services LLC, a United States limited liability company, which is the data controller for the purposes of this policy.
