Studio M, Hackney Depot, 5 Sheep Lane, London E8 4QS, United Kingdom
3. Our representative in the European Union
Mostly Tiny Ltd is established in the United Kingdom. We are appointing a representative in the European Union under Article 27 of the EU GDPR and will name them here. Until then, people in the EU can contact us directly at privacy@mostlytiny.io.
4. 当社が収集する個人データ
当社は直接提供いただく情報（例：account details (name, email); the QR codes, short links, hosted pages and forms you create (destinations and content); Batch QR details (see below); scan analytics about the people who scan your codes (see "Scan data we hold for you"); payment and billing details; product usage; and, only with your consent, how you arrived (see "How we learn where visitors come from")）、mostlyqr.comの使用時に自動的に収集される情報（IPアドレス、デバイスおよびブラウザの種類、表示されたページ、Cookie識別子など）、および第三者から受け取った情報を収集します。
当社は上記のカテゴリーの個人データを本ポリシーに記載された目的のために収集します。
5. データの入手元
当社が直接お客様から個人データを収集しない場合、サービスプロバイダー、分析・広告パートナー、公開されているソース、およびデータの共有を承認した他の第三者などのソースから取得します。
6. データの使用方法と理由
当社は以下の目的でお客様の個人データを使用します：mostlyqr.comおよびサービスの提供、運営、改善、アカウントの作成と管理、お問い合わせへの対応とサポート提供、お客様の体験のカスタマイズ、許可される場合はサービスおよびマーケティングメッセージの送信、サービスの安全性確保と不正行為防止、法的義務の遵守。
7. Scan data we hold for you
When someone scans a MostlyQR code or opens an mqr.sh link on a paid plan, we record for the code's owner: the time; the country and region (not the city); the type of browser, operating system and device (not the full browser identification string); the browser's preferred language; the referring page; an approximate location derived from the IP address and rounded to about 1 km; a salted one-way hash of the IP address, used to count unique scans; and how the scan was routed. We do not store the IP address itself. If a person chooses to share their location on a hosted page, we store it rounded to the same ~1 km. On the free plan we keep only a scan count and the time of the last scan.
We process scan data and form submissions on behalf of the code's owner, who is the controller, under our Data Processing Agreement. If the owner connects an integration — their own webhook, or Meta's Conversions API — we send scan events to that recipient on their instruction; it is their recipient, not ours. If the owner has set a webhook to receive exact location, a location the scanner chose to share is forwarded to it unrounded (we do not store it). If you scanned a code, contact the business that published it first.
8. Batch QR details
A Batch QR code gives each person or product in a list its own code. The details you add to each one — for example a name, title or photo, which can appear on that person's profile page — are held on behalf of the account owner, who is the controller, under our Data Processing Agreement. Profile pages are not listed in search engines and their addresses cannot be guessed.
When the owner deletes a person or their account, those details are erased. When a batch is archived, its details are erased 30 days later. An erased person's code keeps working, but points to the batch's archive page and shows none of their details. If you are in someone's batch, contact the business that created it first.
9. The free QR code checker
The QR code checker at mostlyqr.com/qr-code-checker works without an account. If you upload a photo, the code in it is read inside your browser; the photo is never sent to us. We receive only the link the code contains (or the link you paste). Our servers then follow that link and any redirects once, to show you where it ends up, and send the result back to you. The websites along the way see a request from our servers, identified as "MostlyQR-LinkCheck/1.0 (+https://mostlyqr.com/qr-code-checker)". We do not keep the link or the result.
To keep the checker free, we limit how often it can be used. We count your requests under a keyed hash of your IP address, a scrambled form that cannot be turned back into the address without a secret key we hold, and each count is deleted automatically after its one-hour window, usually within about two days. We do this in our legitimate interest in preventing abuse of a free service.
10. How we learn where visitors come from
Fathom Analytics counts visits to mostlyqr.com without cookies and without identifying you, including which website, campaign or AI assistant referred a visit. In the UK we rely on the statistical-purposes exception in the Privacy and Electronic Communications Regulations. You can object at any time by switching off "Analytics" in Cookie settings, which turns Fathom off for your browser.
We also keep our own anonymous daily totals of visitors who arrive from an advert: how many land, open our editor, sign up and buy, by ad platform and landing page. The ad platform and page name travel in the web address of our own pages; nothing is stored on or read from your device, no cookie is used, and the totals are never linked to you or your account. Because no storage on your device is involved, this counting continues whatever you choose in Cookie settings.
If you accept Analytics or Marketing cookies, our site also remembers in your browser how you first and most recently arrived (campaign tags, the referring site and the page you landed on) and attaches it to your account when you sign up, so we can see which channels bring us customers. If you do not accept, we keep none of this. The one exception is a referral code, if you followed a friend's referral link: we keep it only to credit that referral.
When you sign up, subscribe or cancel, our servers record that event against your account in PostHog (EU), to measure how our business is doing. We rely on our legitimate interests for this; you can object by emailing privacy@mostlytiny.io.
11. Emails we send you
We email you what you need to use MostlyQR: sign-in links, receipts, billing and security notices, and messages about your account. These are part of the service, so you cannot turn them off while your account is open.
We may also send you tips and offers about MostlyQR (onboarding tips, a note when you reach a free-plan limit, and a note if you cancel). The sign-up form has a box for these, ticked by default: untick it and we never send them. In the UK this is the "soft opt-in" in regulation 22 of the Privacy and Electronic Communications Regulations; our lawful basis under the UK GDPR is our legitimate interest in telling customers about the product they signed up for, and you can object at any time.
We email you about other Mostly Tiny products (MostlyPDF, MostlySign, MostlyPrivacy, MostlyRender and Vekta) only if you asked us to, by ticking a box that is never ticked for you, either when you sign up or later in a product. Our lawful basis is your consent. We send at most one such email a month across all of them.
Every marketing email says why you are getting it, has an unsubscribe link, and supports your email app's one-click unsubscribe button. One click stops that kind of email; the linked preferences page lets you choose exactly what you get, or stop all marketing email from every Mostly Tiny product at once. You can also change this in your Mostly Tiny account at id.mostlytiny.io/settings. Withdrawing is as easy as agreeing, and never affects service email.
To show we had your agreement, we record each choice: which box, the exact wording you saw, when, and a keyed one-way hash of your IP address. We store your choices against a one-way hash of your email address. If an address bounces permanently or a message is reported as spam, we stop all marketing email to it. Our do-not-email list keeps only that hash, never your address, so it continues to protect you after you close your account.
12. 処理の法的根拠
EU GDPR または UK GDPR が適用される場合、私たちはArticle 6に基づく1つ以上の正当な法的根拠に基づいてあなたの個人データを処理します：あなたの同意、契約の履行、法的義務の遵守、重大な利益の保護、公共の利益のためのタスク実行、または当社の正当な利益（または第三者の利益）。ただし、あなたの利益または権利が優先される場合を除きます。
正当な利益に頼る場合、これには当社のサービスの運営とセキュリティ確保、使用方法の理解、および限定的なマーケティングが含まれます。あなたはいつでも異議を唱えることができます。Article 9に基づく個人データの特別なカテゴリー（例えば健康またはバイオメトリクスデータ）を処理する場合、私たちはあなたの明示的な同意または法律で許可されている別の条件でのみこれを行います。
13. あなたのデータを誰と共有するか
私たちは次の者と個人データを共有します：当社に代わってmostlyqr.comを運営するサービスプロバイダーとプロセッサー（例えばGoogle Firebase and Google Cloud: hosting, sign-in, database, functions (where, see "Where your data is stored"); Cloudflare: security and approximate location for mqr.sh scan links; Stripe: payments; Fathom Analytics: cookie-free statistics; PostHog (EU): product analytics; Resend: email; Google Safe Browsing and Web Risk: malware/phishing checks on QR destinations; and our own Mostly Tiny services MostlyID, MostlyPrivacy, MostlyRender and Vekta; the unpkg and jsDelivr CDNs and Google Fonts, which serve code and fonts to your browser in the dashboard and so see its IP address）で、当社の指示に従ってのみこれを使用できる者；必要に応じて、専門的アドバイザー、支払いプロバイダー、および法執行機関または規制当局；ならびに合併または買収などの企業取引の当事者。私たちはあなたの個人データを販売しません。
14. Advertising and measuring our adverts
We may advertise MostlyQR on Google, on Microsoft Advertising (Bing, Microsoft Copilot and partner sites) and in ChatGPT. Only if you accept "Marketing" cookies do we load those platforms' tags and, when you arrive from one of our adverts, keep the click identifier the platform added to the link (gclid, gbraid or wbraid for Google; msclkid for Microsoft; oppref for ChatGPT).
If you then subscribe, we tell only the platform whose advert you clicked that it led to a purchase: the click identifier, the time, the value and currency, and — for matching — your email address as a one-way SHA-256 hash. We never send your raw email address, the QR codes you create or your scan data.
Our legal basis is your consent. You can withdraw it at any time in Cookie settings: we then delete the click identifier from your browser and report nothing further, including for a subscription that starts after you withdrew.
Google receives this data under the Google Ads Data Processing Terms (as our processor for enhanced conversions, and as an independent controller for its advertising services); Microsoft and OpenAI receive it as independent controllers. Their privacy notices: policies.google.com/privacy, privacy.microsoft.com/privacystatement and openai.com/policies/privacy-policy. All three are in the United States; transfers rely on the UK Extension to the EU-US Data Privacy Framework where the recipient is certified, and otherwise on the UK International Data Transfer Addendum to the EU Standard Contractual Clauses.
15. 国際的なデータ転送
当社のサービスプロバイダーの一部は、EEA、英国、またはオーストラリアの外を含め、あなたの国の外に所在しています。個人データを国際的に転送する場合、私たちは正当な転送メカニズム（例えば適切性決定、EU標準契約条項（該当する場合はUK国際データ転送補遺付き）、または法律で許可されている別の保護手段）に頼り、あなたのデータを保護するための措置を講じます。詳細はprivacy@mostlytiny.ioへのリクエストで利用可能です。
16. Where your data is stored
MostlyQR runs on Google Cloud and Firebase: database in the EU (eur3 multi-region: Belgium and the Netherlands, with a witness replica in Finland); server functions in the UK (europe-west2, London); uploaded logos, images and print assets in the United States (us-east1).
Sign-in uses Firebase Authentication, which Google runs only in the United States, and a Mostly Tiny account you sign in with is held by Mostly Tiny ID, whose database is in the United States. Our website is served from Google's global network (Firebase Hosting).
Transfers from the UK to the EU are approved under UK law, which treats transfers to EEA states as approved (Data Protection Act 2018, Schedule 21). Transfers to Google LLC in the United States rely on the UK Extension to the EU-US Data Privacy Framework (and, for data under the EU GDPR, on the EU-US Data Privacy Framework), to both of which Google LLC is certified. If you are in the EU, your personal data reaches our servers in the UK under the European Commission's adequacy decision for the UK (Implementing Decision (EU) 2021/1772, as amended by Implementing Decision (EU) 2025/2574).
17. お客様のデータを保持する期間
当社は、本ポリシーに記載された目的に必要な期間のみ個人データを保持し、その後削除または匿名化します。データ保有期間の設定基準には、データの性質と機密性、処理目的、ならびに法的・会計的・報告義務が含まれます(account data until you delete your account; Batch QR details as set out in "Batch QR details"; scan analytics for the account's lifetime, within your plan's limits; how you arrived (if you consented) for the account's lifetime; billing records as tax law requires; and a reported advertising conversion for as long as the subscription it relates to)。
18. 当社がお客様のデータを保護する方法
当社は、転送時の暗号化、アクセス制御、定期的な見直しを含む適切な技術的および組織的措置により、個人データを損失、誤用、不正アクセスから保護します。転送または保存方法は完全に安全とは限らないため、当社は完全なセキュリティを保証できません。
19. クッキーと類似テクノロジー
当社はmostlyqr.comでクッキーと類似テクノロジーを使用しています。使用するクッキーの目的、有効期間、制御方法については、当社のクッキーポリシーをご参照ください。
20. 自動意思決定
当社は、法律で許可されている場合を除き、プロファイリングを含む自動処理のみに基づいて、お客様に関する法的または同様の重大な影響を生じさせる決定を行いません。当社がそうする場合は、お客様にお知らせし、関係するロジックを説明し、人間による確認を受ける権利を提供します。
21. 児童のプライバシー
mostlyqr.comは児童を対象としていません。デジタル同意年齢（GDPR下では16歳、国によっては13歳までの低い年齢）を下回る児童の個人情報は意識的に収集しません。また、16歳未満であることが判明している消費者の個人情報を意識的に販売または共有しません。児童がデータを提供したと考えられる場合は、privacy@mostlytiny.ioまでお問い合わせください。削除いたします。
22. GDPRに基づくあなたの権利
EU または UK GDPR が適用される場合、あなたには次の権利があります。通知を受ける権利、個人データへのアクセス権、不正確なデータの訂正を求める権利、データ削除を求める権利、処理の制限を求める権利、データ移植可能性の権利、および処理への異議申し立て権（ダイレクトマーケティングへの異議申し立てを含む）。同意に基づいて処理が行われている場合、事前に行われた処理に影響を与えることなく、いつでも同意を撤回することができます。
これらの権利を行使するには、privacy@mostlytiny.ioまでお問い合わせください。1か月以内に対応いたします。複雑または多数のリクエストについては最大2か月延長される可能性がありますが、その場合は最初の1か月以内にお知らせします。また、データ保護監督当局に苦情を申し立てる権利も有しています。
23. 英国の監督当局
英国にお住まいの場合、UK GDPR および2018年データ保護法が適用され、ico.org.ukの情報コミッショナー事務所（ICO）に苦情を申し立てることができます。
24. How to complain to us
If you are unhappy with how we have handled your personal data, email privacy@mostlytiny.io with "Complaint" in the subject. We will acknowledge your complaint within 30 days, look into it, and tell you the outcome without undue delay. You can also complain to the Information Commissioner's Office at any time.
25. If you are in the United States
We do not sell personal information. Measuring our adverts, described above, can count as "sharing" under some US state privacy laws; it happens only if you accept Marketing cookies, and we treat a Global Privacy Control signal from your browser as a refusal. To ask what we hold about you, or to have it corrected or deleted, email privacy@mostlytiny.io.
26. ポリシーの変更
このプライバシーポリシーは随時更新される場合があります。更新版は新しい発効日とともにここに掲載し、重大な変更がある場合はお知らせするために合理的な措置を講じます。
27. お問い合わせ
個人データの取り扱いに関する質問、リクエスト、または苦情については、Mostly Tiny Ltdにprivacy@mostlytiny.ioでお問い合わせください。
