1. 政策原文。Google Play 的「Dangerous Products（危险品）」政策（开发者计划政策总页 https://support.google.com/googleplay/android-developer/answer/17517561 ）只有两句话，而两句话都是禁令，不是让你填报的声明：「We don't allow apps that facilitate the sale of explosives, firearms, ammunition, or certain firearms accessories.」（不允许 App 促成爆炸物、枪支、弹药或某些枪械配件的销售。）「We don't allow apps that provide instructions for the manufacture of explosives, firearms, ammunition, restricted firearm accessories, or other weapons. This includes instructions on how to convert a firearm to automatic, or simulated automatic, firing capabilities.」（不允许 App 提供制造爆炸物、枪支、弹药、受限枪械配件或其他武器的说明，包括如何把枪械改装为全自动或模拟全自动射击。）没有「受管制商品申报表」可填，也没有哪个年龄门能解锁购买流程——唯一合规状态就是这个 App 根本不提供这些功能。
2. 「certain firearms accessories」是一份封闭清单，不是模糊感受。同一页给了定义：「Restricted accessories include those that enable a firearm to simulate automatic fire or convert a firearm to automatic fire (for example, bump stocks, gatling triggers, drop-in auto sears, conversion kits), and magazines or belts carrying more than 30 rounds.」读精确一点：Play 的受限清单只针对「全自动改装件」与「30 发以上供弹具」。枪套、清洁套件、瞄具、背带、枪袋不在 Play 这份清单里——但商店政策不覆盖当地法律，目标地区法律仍然适用。而且 Google 明确政策跟着内容走：「Our policies apply to any content your app displays or links to, including any ads it shows to users and any user-generated content it hosts or links to.」（政策适用于你 App 展示或链接到的任何内容，包括投放给用户的广告与托管的用户生成内容）（Policy Coverage：https://support.google.com/googleplay/android-developer/answer/9899816）。
3. 「facilitate the sale（促成销售）」到底抓什么。「Facilitate」这个词才是把目录型 App 变成违规的关键。实务中被判定违规的形态是：App 内购物车/结账流程能完成枪械、弹药、爆炸物或受限配件的交易；经销商/FFL 定位器不只是展示电话与官网，而是能把订单导过去；分类信息、跳蚤市场、点对点板块让用户互相成交；以及拿佣金的联盟/返利链接。Illegal Activities 政策给出通则：「We don't allow apps that facilitate or promote illegal activities.」（不允许 App 促成或推广非法活动）（https://support.google.com/googleplay/android-developer/answer/9878877）。
4. 「说明」那半句才是 3D 打印与复装内容的死线。因为禁令写的是「instructions for the manufacture of explosives, firearms, ammunition, restricted firearm accessories, or other weapons」，被覆盖的包括：3D 打印枪的 CAD/STL 文件与组装教程（Google Ads 政策把 3D-printed guns 明确列为禁投类目）、机加工与装配教程、弹药复装（reloading）配方，以及任何最终指向「能用起来的枪或爆炸物」的教程。它还明确包含「how to convert a firearm to automatic, or simulated automatic, firing capabilities」——所以一篇「随便讲讲」的全自动改装教程，和卖枪的购物车是同一条违规，而清单里的速射配件正是这类教程要改装出来的东西。删掉购物车却留着改装手册，等于没修。
5. 狩猎、射击、靶场类游戏通常能过——靠 Violence 政策，而不是 Dangerous Products。Violence 政策原文：「We don't allow apps that depict or facilitate gratuitous violence or other dangerous activities. Apps that depict fictional violence in the context of a game, such as cartoons, hunting or fishing, are generally allowed.」（不允许 App 描绘或促成无端暴力及其他危险行为；游戏语境下的虚构暴力，例如卡通、狩猎、钓鱼，一般是允许的。）所以狩猎/打靶游戏一般可以上架；写实血腥暴力、对真人真动物的威胁、自伤自杀内容，以及为真实袭击做准备、策划或美化的内容（Violent Extremism）则不行。分界线是「游戏内的虚构」对「写实或鼓吹」，而不是「画面上有没有武器」。
6. 使用真实枪厂品牌是完全另一条雷。在标题、图标、截图或游戏物品里使用真枪厂的名称、字标或外观，按 Intellectual Property 政策处理（https://support.google.com/googleplay/android-developer/answer/9888072），与 Dangerous Products 无关——这就是射击游戏普遍使用虚构枪名的原因。同理，借警察/军队/政府徽章装「官方」，属于 Impersonation 政策：「Don't imply that your app is related to or authorized by someone that it isn't.」官方违规示例：「The app is using a national emblem and misleading users into believing it is affiliated with government.」（https://support.google.com/googleplay/android-developer/answer/9888374）如果确实是某机构或持牌经销商的官方产品，必须能出具授权，而且 App 仍然不得提供 Dangerous Products 政策禁止的销售功能。
7. 年龄信号靠内容分级，不靠「屏蔽未成年人」工具。武器内容不在 Age-Restricted Content and Functionality 清单内——那份清单覆盖的是真钱赌博、约会/婚恋撮合、随机聊天、匿名聊天类 App（https://support.google.com/googleplay/android-developer/answer/16302250）。武器内容走内容分级：官方原文「Misrepresentation of your app's content may result in removal or suspension, so it is important to provide accurate responses to the content rating questionnaire」（内容分级申报不实可能导致下架或封号，因此问卷必须如实填写）；分级「help filter or block your content in certain territories or to specific users where required by law」（帮助在法律要求的地区或人群层面过滤内容）；「Apps without a content rating will be removed from the Play Store」（没有内容分级的 App 会被下架）（https://support.google.com/googleplay/android-developer/answer/9898843）。在 IARC 问卷里如实回答武器相关题目，才是这个本来合规的狩猎/模拟类 App 不被以「分级与内容不符」下架的关键。
8. 广告网络的规则比商店更严，而且就在你 App 里面生效。Google Ads 政策（由 AdMob 执行）的 Guns, gun parts, and related products 禁投类目列举了大量例子：「Handguns, rifles, shotguns, hunting guns, functioning antique guns, airsoft guns, paintball guns and activity as a service, bb guns, 3D-printed guns」、「Ammunition, ammunition clips, silencers, tripods and bipods for guns, stocks, conversion kits, gun-grips, scopes and sights, bump stocks」，以及「Ads for instructions on the assembly or enhancement of the functionality of firearms」（https://support.google.com/adspolicy/answer/16489226）。Other weapons 政策则禁「Ads for knives that are designed or promoted in modern-day usage as products that can be used to injure an opponent in sport, self-defense, or combat」（弹簧刀、格斗刀、手杖剑、蝴蝶刀、军刀、推刺匕首、投掷斧）、「throwing stars, brass knuckles, tasers, pepper spray」，以及这些物品的组装/增强/获取类教学内容（https://support.google.com/adspolicy/answer/16489730）。注意这个落差：瞄具在世界多数地区可合法销售、也不在 Play 受限配件清单里，但在你 App 的广告位推广它，广告网络照样禁止。另外 App 内广告「must not be significantly more mature in content than the primary content within the app itself」（广告的成熟度不得显著高于 App 主体内容）（https://support.google.com/googleplay/android-developer/answer/9898843）。正确做法是在聚合后台直接屏蔽 firearms/weapons/格斗刀类目，而不是等网络方来抓。
9. 执法机制要按最坏情况预设。Enforcement Process 原文：判定会综合「app metadata (for example, app title, description), in-app experience, account information (for example, past history of policy violations), any third-party code in apps, and other information provided through reporting mechanisms」；并明确「removal or administrative notices may not indicate each and every policy violation present in your account, app, or broader app catalog」（下架通知未必列全你账号与全部 App 的每一处违规）；「Failure to address policy violations in your account and all of your apps may result in additional enforcement actions」（不整改账号内全部违规会招致进一步执法）（https://support.google.com/googleplay/android-developer/answer/9899234）。申诉次数是有限的：「You may submit one appeal per app removal, suspension, or other enforcement action.」（每次下架、暂停或其他执法只有一次申诉机会）（https://support.google.com/googleplay/android-developer/answer/2477981）。第三方代码同样由你负责——一个允许用户发布枪械信息的市场/分类/社交 SDK，违规算在你 App 头上。
10. 提交前自查清单。删掉任何能完成枪械/弹药/爆炸物/受限配件成交的购物车、结账、订单跳转、点对点挂牌路径，包括联盟链接与跳向经销商站的「立即购买」深链；清掉制造类内容：3D 打印 CAD/STL 文件、组装与机加工教程、复装配方、以及每一个全自动/模拟全自动改装讲解；按 User Generated Content 政策审核论坛、评论、分类与私信，使其无法被用来撮合交易；商店文案只描述 App 做什么，不要暗示可以购买；武器内容如实填写内容分级问卷；不用真实厂商品牌，也不用国家/军队徽章；广告位不留枪械、配件、格斗刀创意；在法律限制该题材的地区做区域性限投；如果同一交易功能存在于网站，确保 App 本体不承载该交易。开发者侧的武器类拒审/申诉案例汇总：https://www.reddit.com/r/androiddev/search/?q=weapons+app+play+store+policy+rejection
